Abstract

A vehicle includes an inverted suspension and a wheel speed sensor and a sensor wire. At least a portion of a left wheel speed sensor is disposed inwards of an outer edge of a left front inner tube, and at least a portion thereof is provided between a left front imaginary line and a left rear imaginary line when seen from the direction of the left wheel axis and disposed above a lower end of a left shock absorber. A left sensor wire crosses the left front imaginary line or the left rear imaginary line below either of a lower end of a left front outer tube and a lower end of a left rear outer tube. At least a portion of a left lower restrictor is provided on a left inner connector in a position located ahead of the left front imaginary line or behind the left rear imaginary line.

First claim

What is claimed is:

1. A vehicle comprising: a body frame that is able to lean to a right of the vehicle when the vehicle turns right and lean to a left of the vehicle when the vehicle turns left;
a right front wheel that rotates about a right wheel axis;
a left front wheel provided on a left of the right front wheel in relation to a left-and-right direction of the body frame and that rotates about a left wheel axis;
a right shock absorber that supports the right front wheel at a lower portion thereof so as to enable the right front wheel to be displaced relatively upwards;
a left shock absorber that supports the left front wheel at a lower portion thereof so as to enable the left front wheel to be displaced relatively upwards; and
a linkage provided on the body frame so as to turn and which supports an upper portion of the right shock absorber at a right portion thereof and supports an upper portion of the left shock absorber at a left portion thereof so as to enable the right front wheel and the left front wheel to be displaced relatively in relation to an up-and-down direction of the body frame; wherein
the right shock absorber includes:
a right front telescopic element including a right front outer tube that extends in a direction of a right extending and contracting axis that extends in the up-and-down direction of the body frame and a right front inner tube that is inserted into the right front outer tube and which extends in the direction of the right extending and contracting axis so that a lower end portion thereof is provided below a lower end portion of the right front outer tube;
a right rear telescopic element including a right rear outer tube that is provided behind the right front outer tube in relation to a front-and-rear direction of the body frame and which extends in the direction of the right extending and contracting axis and a right rear inner tube that is inserted into the right rear outer tube and which extends in the direction of the right extending and contracting axis so that a lower end portion thereof is provided below a lower end portion of the right rear outer tube; and
a right inner connector that connects a lower portion of the right front inner tube and a lower portion of the right rear inner tube together;

the left shock absorber includes:
a left front telescopic element including a left front outer tube that extends in a direction of a left extending and contracting axis that extends in the up-and-down direction of the body frame and a left front inner tube that is inserted into the left front outer tube and which extends in the direction of the left extending and contracting axis so that a lower end portion thereof is provided below a lower end portion of the left front outer tube;
a left rear telescopic element including a left rear outer tube that is provided behind the left front outer tube in relation to the front-and-rear direction of the body frame and which extends in the direction of the left extending and contracting axis and a left rear inner tube that is inserted into the left rear outer tube and which extends in the direction of the left extending and contracting axis so that a lower end portion thereof is provided below a lower end portion of the left rear outer tube; and
a left inner connector that connects a lower portion of the left front inner tube and a lower portion of the left rear inner tube together;

at least one of a condition (A) and a condition (B) below is satisfied;
condition (A) includes:
a structure that the vehicle includes:
a right wheel speed sensor including a right wheel speed detector that detects a wheel speed of the right front wheel and a right sensor housing that holds the right wheel speed detector; and
a right lower restrictor that restricts or prevents deformation of a right sensor wire that extends from the right wheel speed sensor to an engine controller provided on the body frame so that the right sensor wire is prevented from coming into contact with at least the right front outer tube and the right rear outer tube when the right shock absorber is operated;

a structure that the right wheel speed sensor is such that, when looking from a front of the vehicle and the vehicle is standing upright and not steered at all, at least a portion of the right wheel speed sensor is disposed closer to the right front wheel than an outer edge of a side of the right front inner tube which is located opposite to the right front wheel in relation to the direction of the right wheel axis, and that when looking at the vehicle from the direction of the right wheel axis, at least a portion of the right wheel speed sensor is between a right front imaginary line that extends along a rear edge of the right front inner tube and a right rear imaginary line that extends along a front edge of the right rear inner tube and is disposed above a lower end of the right shock absorber in relation to an up-and-down direction of the right extending and contacting axis when looking at the vehicle from the direction of the right wheel axis;
a structure that the right sensor wire crosses the right front imaginary line or the right rear imaginary line below either of a lower end of the right front outer tube and a lower end of the right rear outer tube which is located lower than the other of the lower end of the right front outer tube and the lower end of the right rear outer tube when the right shock absorber extends to its maximum extent; and
a structure that, when looking at the vehicle from the direction of the right wheel axis, at least a portion of the right lower restrictor is provided on the right inner connector or a member that is not displaced relative to the right inner connector in a position that is located ahead of the right front imaginary line in relation to the front-and-rear direction of the body frame or a position that is located behind the right rear imaginary line in relation to the front-and-rear direction of the body frame;
condition (B) includes:
a structure that the vehicle includes:
a left wheel speed sensor including a left wheel speed detector that detects a wheel speed of the left front wheel and a left sensor housing that holds the left wheel speed detector; and
a left lower restrictor that restricts or prevents deformation of a left sensor wire that extends from the left wheel speed sensor to the engine controller so that the left sensor wire is prevented from coming into contact with at least the left front outer tube and the left rear outer tube when the left shock absorber is operated;

a structure that the left wheel speed sensor is such that, when looking from a front of the vehicle and the vehicle is standing upright and not steered at all, at least a portion of the left wheel speed sensor is disposed closer to the left front wheel than an outer edge of a side of the left front inner tube which is located opposite to the left front wheel in relation to the direction of the left wheel axis and that when looking at the vehicle from the direction of the left wheel axis, at least a portion of the left wheel speed sensor is between a left front imaginary line that extends along a rear edge of the left front inner tube and a left rear imaginary line that extends along a front edge of the left rear inner tube and is disposed above a lower end of the left shock absorber in relation to an up-and-down direction of the left extending and contacting axis when looking at the vehicle from the direction of the left wheel axis;
a structure that the left sensor wire crosses the left front imaginary line or the left rear imaginary line below either of a lower end of the left front outer tube and a lower end of the left rear outer tube which is located lower than the other of the lower end of the left front outer tube and the lower end of the left rear outer tube when the left shock absorber extends to its maximum exte
