Abstract

A waterproof cover is attached to a portion of a body frame positioned behind a rear end of a left side member and ahead of left and right engine supports of the body frame when looking at a vehicle standing in an upright state from the left of the vehicle, and at least a portion of the waterproof cover overlaps at least one of a right side member and the left side member when looking at the vehicle from the front of the vehicle.

First claim

What is claimed is:

1. A vehicle comprising:
a body frame that leans right when the vehicle turns right and leans left when the vehicle turns left;
a right front wheel that rotates about a right axle extending in a direction of a right axle axis;
a left front wheel provided leftward of the right front wheel and that rotates about a left axle extending in a direction of a left axle axis;
a linkage that changes a relative position of the right front wheel and the left front wheel in an up-and-down direction of the body frame as the body frame leans;
a right shock absorber that supports the right front wheel at a lower portion thereof and absorbs a relative displacement of the lower portion to an upper portion thereof along a right extension and contraction axis extending in the up-and-down direction of the body frame;
a left shock absorber that supports the left front wheel at a lower portion thereof and absorbs a relative displacement of the lower portion to an upper portion thereof along a left extension and contraction axis extending in the up-and-down direction of the body frame;
an engine fixed to an engine support of the body frame so as not to be displaced; and
a body cover that covers at least a portion of the linkage; wherein
the linkage includes:
a right side member that supports the upper portion of the right shock absorber such that the upper portion is able to turn about a right steering axis;
a left side member that supports the upper portion of the left shock absorber such that the upper portion is able to turn about a left steering axis;
an upper cross member that supports an upper portion of the right side member at a right end portion of the upper cross member such that the upper portion is able to turn about a right upper axis extending in a front-and-rear direction of the body frame, to support an upper portion of the left side member at a left end portion of the upper cross member such that the upper portion is able to turn about a left upper axis located parallel to the right upper axis, and is supported on the body frame at a middle portion of the upper cross member so as to turn about a middle upper axis located parallel to the right upper axis and the left upper axis; and
a lower cross member that supports a lower portion of the right side member at a right end portion of the lower cross member such that the lower portion is able to turn about a right lower axis located parallel to the right upper axis, support a lower portion of the left side member at a left end portion of the lower cross member such that the lower portion is able to turn about a left lower axis located parallel to the left upper axis, and is supported on the body frame at a middle portion of the lower cross member so as to turn about a middle lower axis located parallel to the middle upper axis; and
the vehicle satisfies at least one of a condition (A) and a condition (B) below:
the condition (A): a right waterproof cover is located behind a rear end of the right side member and ahead of the engine support of the body frame when the vehicle standing in an upright state is seen from the right of the vehicle, and at least a portion of the right waterproof cover overlaps the right side member when the vehicle is seen from the front of the vehicle; and
the condition (B): a left waterproof cover is located behind a rear end of the left side member and ahead of the engine support of the body frame when the vehicle standing in an upright state is seen from the left of the vehicle, and at least a portion of the left waterproof cover overlaps the left side member when the vehicle is seen from the front of the vehicle.

2. The vehicle according to claim 1 , wherein
the engine includes a crankcase and a cylinder block mounted on an upper portion of the crankcase and extending upwards in the up-and-down direction of the body frame; and
the body frame supports the engine by the engine support being connected to the cylinder block.

3. The vehicle according to claim 1 , wherein the body frame includes:
a link support that supports the upper cross member and the lower cross member;
a right frame extending from the link support rearwards in the front-and-rear direction of the body frame; and
a left frame extending from the link support rearwards in the front-and-rear direction of the body frame; wherein the engine support is provided on the right frame and the left frame; and
the condition (A) further includes a condition that the right waterproof cover is located rightward of the right frame in a left-and-right direction of the body frame; and
the condition (B) further includes a condition that the left waterproof cover is located leftward of the left frame in the left-and-right direction of the body frame.

4. The vehicle according to claim 1 , wherein
the condition (A) further includes a condition that the right waterproof cover is located in a plane parallel to a turning locus of the linkage on a front surface of the right waterproof cover in the front-and-rear direction of the vehicle body; and
the condition (B) further includes a condition that the left waterproof cover is located in a plane parallel to a turning locus of the linkage on a front surface of the left waterproof cover in the front-and-rear direction of the body frame.

5. The vehicle according to claim 1 , further comprising:
a fuel tank disposed directly above the engine; wherein
the body cover includes an upper cover that covers the fuel tank; and
the condition (A) further includes a condition that the right waterproof cover is separate from the upper cover; and
the condition (B) further includes a condition that the left waterproof cover is separate from the upper cover.
