SUMMARY OF THE INVENTION In order to solve the above-mentioned problems, a motorcycle according to the present invention is provided with a motor vehicle near a center of gravity of a vehicle body.
A two- or three-wheeled vehicle in which a cover is provided to cover the lower part side and a protector rubber is provided on the side surface of the cover so as to protrude toward the side wall, the protector rubber is attached to the left and right side surfaces of the vehicle body below the seat, and the center of gravity is located below the side view. One at a time in the center of the vehicle body, and each is viewed from the cover in front view.
With the outermost, and these protectors
Each of the rubbers is supported by a frame passing below the floor.

[0005]

[Function] The protector rubber is located near the center of gravity and below the center of the vehicle body when viewed from the side, and below the center of gravity of the vehicle body when viewed from the front.
The load applied to the side of the vehicle body tends to concentrate on the protector rubber because the outermost portion protrudes from the cover that covers the side of the protector. Moreover, since this portion is close to a frame that passes below the floor, the protector rubber can be easily supported by this frame. Therefore, it is easy to provide a mounting structure that can sufficiently withstand a large load.
Moreover, the number and size of the components used can be minimized.

[0006]

The protector rubber according to the present invention is provided near the center of gravity and below the center of the vehicle body in a side view , as well as in the front.
From the cover that covers the side below the center of gravity of the body
Since it is provided so as to protrude outward and is supported by a frame that passes below the floor, it becomes easy to concentrate the load applied to the side of the vehicle body to the protector rubber at one place on the side of the vehicle body. Therefore, only one protector rubber is required for one side of the vehicle body. As a result, the number of protector rubbers can be reduced as much as possible, and the vehicle body structure can be simplified and the weight can be reduced.
