Abstract

At least a portion of a detecting portion of a front wheel rotation speed detector is supported on one front telescopic element of a shock absorbing device and is positioned in, as viewed in the direction of a wheel axis, an area defined by a front imaginary line which passes a front end of the shock absorbing device and which is parallel to a steering axis and a rear imaginary line which passes a rear end of the shock absorbing device and which is parallel to the steering axis in a perpendicular or substantially perpendicular direction to the wheel axis and the steering axis, an area located inwards of an outer shape of a wheel, and an area which is located outside an area defined between the front and rear telescopic elements.

First claim

The invention claimed is:

1. A vehicle comprising:
a body frame that leans to a right of the vehicle when the vehicle turns right and leans to a left of the vehicle when the vehicle turns left;
a right front wheel and a left front wheel aligned in a left-and-right direction of the body frame and which each include a tire and a wheel that supports the tire;
a suspension device including a right shock absorbing device and a left shock absorbing device that support the right front wheel and the left front wheel so as to rotate about wheel axes thereof, respectively, each of the right shock absorbing device and the left shock absorbing device including a front telescopic element and a rear telescopic element aligned in a front-and-rear direction of the body frame and a connecting portion that connects the front telescopic element and the rear telescopic element together and supports the right shock absorbing device and the left shock absorbing device on the body frame so that the right shock absorbing device and the left shock absorbing device turn individually about steering axes thereof which extend in a direction perpendicular or substantially perpendicular to the wheel axes and are able to be displaced in an up-and-down direction of the body frame; and
a front wheel rotation speed detector which includes a detected portion which rotates together with one front wheel of the right front wheel and the left front wheel and a detecting portion which is provided on one shock absorbing device of the right shock absorbing device and the left shock absorbing device which supports the one front wheel to measure a rotation speed of at least the one front wheel; wherein
at least a portion of the detecting portion of the front wheel rotation speed detector is supported on the front telescopic element or the rear telescopic element of the one shock absorbing device and is positioned, as viewed in a direction of the wheel axis, in an area which is defined by a front imaginary line which passes a front end of the one shock absorbing device and which is parallel or substantially parallel to the steering axis and a rear imaginary line which passes a rear end of the one shock absorbing device and which is parallel or substantially parallel to the steering axis, an area which is located inwards of an external shape of the one front wheel, and an area which is located outside an area defined between the front telescopic element and the rear telescopic element of the one shock absorbing device.

2. The vehicle according to claim 1 , wherein
an upper portion of the steering axis is positioned farther rearwards than a lower portion thereof in the front-and-rear direction of the body frame when the vehicle is in the upright state; and
at least a portion of the detecting portion of the front wheel rotation speed detector is provided in an area which is located behind the front end of the one shock absorbing device and an area which is located outside of an area defined between the front telescopic element and the rear telescopic element of the one shock absorbing device when the vehicle is in the upright state.

3. The vehicle according to claim 1 , wherein
an upper portion of the steering axis is positioned farther rearwards than a lower portion thereof in the front-and-rear direction of the body frame when the vehicle is in the upright state; and
at least a portion of the detecting portion of the front wheel rotation speed detector is provided in an area which is located behind a front end of the one shock absorbing device, an area which is located ahead of a lower end of the one shock absorbing device, and an area which is located outside an area defined between the front telescopic element and the rear telescopic element of the one shock absorbing device when the vehicle is in the upright state.

4. The vehicle according to claim 1 , wherein
an upper portion of the steering axis is positioned farther rearwards than a lower portion thereof in the front-and-rear direction of the body frame when the vehicle is in the upright state; and
at least a portion of the detecting portion of the front wheel rotation speed detector is provided in an area which is located above a lower end of the one shock absorbing device in relation to an up-and-down direction of the body frame and an area which is located outside an area defined between the front telescopic element and the rear telescopic element of the one shock absorbing device when the vehicle is in the upright state.

5. The vehicle according to claim 1 , wherein
an upper portion of the steering axis is positioned farther rearwards than a lower portion thereof in the front-and-rear direction of the body frame when the vehicle is in the upright state; and
at least a portion of the detecting portion of the front wheel rotation speed detector is provided in an area which is located above a lower end of the rear telescopic element of the one shock absorbing device in relation to an up-and-down direction of the body frame, an area which is located below a front end of the front telescopic element of the one shock absorbing device in relation to the up-and-down direction of the body frame, and an area which is located outside an area defined between the front telescopic element and the rear telescopic element of the one shock absorbing device when the vehicle is in the upright state.
