2. Description of the Related Art Motorcycles or three- and four-wheeled vehicles (bulgy vehicles) straddle a saddle-type seat mounted on the upper part of a frame and are mounted on a step having both feet attached to both sides of the frame. It is configured to be steered by gripping the bar handle. In such a riding type vehicle, a fuel tank is generally mounted on the front side of a seat, and detachable side covers are mounted on both sides of the vehicle. This side cover is opened when checking or replacing equipment inside the vehicle, and its mounting position is usually adjacent to the seat, such as under the seat or between the front of the seat and the fuel tank or front cover. Selected for location.

By the way, in the above side cover,
In some cases, a surface pattern and texture equivalent or similar to that of seat leather are required for design reasons of giving a sense of unity between the seat portion and the side cover portion. Therefore,
Conventionally, a side cover having a structure similar to a seat has been used to meet such a demand. That is,
As shown in the cross-sectional view of the side cover in FIG. 6, an intermediate member 2 such as urethane foam is formed on a base body 1 made of a hard resin such as ABS and the like, and a sheet leather is formed thereon. A side cover having a structure for covering, assembling, and fixing 3 is used. Such a conventional side cover is disclosed, for example, in Japanese Patent Application No. 60-234 of the present applicant.
No. 894 and the like.
