Description

[Detailed Description of the Invention] The present invention relates to a mounting structure for a side cover that covers a battery box or an air cleaner case of a motorcycle.

In general, parts of motorcycles that do not require cooling by outside air, such as the battery box or air cleaner case, are gathered in one place and covered with side covers to improve appearance, protect them from the outside, and also keep them away from dust. etc., to prevent it from adhering to it.

Conventionally, to install such a side cover, a special stay for attaching the side cover is provided on the vehicle body frame, a hole is formed in this stay, a grommet is attached to this hole, and a protrusion provided on the side cover is inserted into the grommet. I'm trying to fit it in.

However, since the side cover covers the battery box, air cleaner case, etc., its shape is limited by the shape of the battery box, etc., and it also has a portion that bulges out to the outside of the vehicle body. Therefore, if a special stay is provided on the frame in order to fix the side cover of this shape to the vehicle body, the stay becomes long or it has to be curved to escape parts such as the battery box, which is cumbersome to manufacture. . It is also possible to lengthen the protrusions provided on the side cover, but in this case, the side cover cannot be firmly attached, and may wobble or come off after attachment.

The present invention has been developed in view of the conventional problems as described above, and is a side cover mounting method for motorcycles that allows the side cover to be securely and firmly attached to the vehicle body without providing any dedicated mounting stays on the frame. The purpose is to provide structure.

In order to achieve the above object, the present invention provides a side cover that covers the outside of an air cleaner case attached to a frame, the side cover having a shape that fits between a center tube and a subtube of the frame, and A mounting protrusion is provided on the back surface, a lid member is provided at the opening on the side cover side of the air cleaner case, and a lid member is integrally molded on the outer periphery of the lid member, and both open ends are provided on the side surface facing the side cover of the air cleaner case. Provide a U-shaped cross section that abuts the
The gist thereof is that a hole is formed in the U-shaped cross section at a position facing the protrusion of the side cover, through which the protrusion of the side cover is held so as to be insertable and removable via an elastic ring.
