Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a scooter type motorcycle or a motorcycle tricycle side cover mating structure, and particularly to an assembly workability when a side cover is divided into a cover body and a skirt. Regarding improvement.

[Conventional technology]

In general, scooter-type motorcycles have a footrest mounted on a front upper surface of a main frame and a side cover surrounding an engine mounted on a lower rear portion thereof. Conventionally, this side cover is divided into a cover main body and left and right skirts located below the cover main body in order to improve engine maintainability and design requirements.

In the case where the side cover is divided as described above, the structure for combining the cover body, the skirt, and the footrest plate has conventionally been such that at least one of these parts is fixed to the main frame and these parts are mutually fixed. It is common to do.

[Problems to be solved by the invention]

In the above-mentioned conventional mating structure, whether or not the footrest plate, the cover body, and the skirt can be accurately assembled is determined as follows.
When the accuracy of the main frame is poor, the accuracy of the mating surface of each part is also reduced, and the appearance is deteriorated and the assemblability is reduced.
Further, since the side cover is fixed to the main frame, there is a problem that the side cover is easily damaged when it falls down or comes into contact with something.

SUMMARY OF THE INVENTION The present invention has been made to solve such a conventional problem, and a scooter-type motorcycle, which can be improved in alignment accuracy without being affected by the accuracy of a body frame, and can be prevented from being damaged, can be prevented. The purpose of the present invention is to provide a side cover mating structure.

[Means for solving the problem]

The present invention provides a scooter-type motorcycle and three-wheeled vehicle in which the side cover is divided into a cover body surrounding a lower portion of a seat, and left and right skirts located below left and right portions of the cover body. Replace the cover body
The left side cover covers the lower left side of the seat, the rear cover covers the lower rear side of the seat, and the right side cover covers the lower right side of the seat. The lower edge of the front cover of the left and right side covers is fixed to the rear edge of the footrest plate fixed to the body frame,
Without fixing the upper part of the rear cover to the vehicle body frame, only the lower part is supported by the vehicle body frame via an elastic body so as to be floatable, and the front edge of the skirt is the left and right sides of the rear edge of the footrest plate. While fixing near the surface cover fixing part,
The upper edge is supported by the lower edges of the left and right side covers.

(Operation) In the scooter type motorcycle two- or three-wheeled vehicle side cover mating structure according to the present invention, the cover body is supported by the body frame such that the rear portion thereof can float, and the skirt is supported by the above-mentioned floatable upper portion. Since the cover body and the skirt are supported by the cover body, the cover body and the skirt are so-called floating supports in which only one portion is fixed to each of the body frame via a footrest plate. Therefore, even if the vehicle body frame has a distortion or the like, the distortion can be absorbed, that is, it is hardly affected by the accuracy of the vehicle body frame, the alignment accuracy is improved, and as a result, the assemblability of the side cover is improved.

Further, when a load is applied from the lateral direction, the load is applied to the floating support such that the entire cover body and skirt can move back and forth and right and left around the front end, and the cover body is moved to the left and right side covers. By being formed integrally with the rear cover and having a shape that is easily elastically deformed, it is efficiently absorbed, and as a result, breakage can be prevented.
