2. Description of the Related Art Conventionally, there is a storage device for a scooter type motorcycle in which a storage box is formed in a rear cover (leg shield) that covers the rear side of a head pipe. Conventionally, as such a storage device, for example, the rear cover is integrally formed so as to extend from the front end of the footboard of the footrest to just below the steering handle, and the middle part of the rear cover in the height direction is expanded rearward. an opening is formed at the upper end of the bulge to make the bulge the rear wall of the storage box, and a separate inner box is placed in front of the bulge to serve as the front wall of the storage box. However, there is a structure in which this is fixed around the bulge of the front cover.

0003

[Problem to be solved by the invention] However, the above conventional
In the case of a structure in which the middle part of the rear cover bulges rearward to form the rear wall of the storage box, the rear cover inevitably becomes a large component extending from the footboard to the vicinity of the handlebar cover. Therefore, the mold for molding the resin for the rear cover becomes larger, increasing the cost of the mold itself, and requires a long time to cool down during resin molding, which poses problems when trying to improve production efficiency. . Further, in the case of the conventional structure, since the welded portion between the inner box and the rear cover is visible from the outside through the opening, there is also a problem that the appearance of the storage box portion is degraded. Furthermore, in the case of the above conventional structure, since a large opening is formed in the rear bulge of the rear cover, there is a problem that the rigidity of the rear cover itself tends to decrease. The present invention was made in view of the above-mentioned conventional situation, and by downsizing the resin molding mold, it is possible to reduce the mold cost, shorten the cooling time, improve production efficiency, and reduce the appearance. It is an object of the present invention to provide a storage device for a scooter type motorcycle that can avoid this and improve rigidity.

0004

[Means for Solving the Problems] The present invention provides a storage device for a scooter type motorcycle in which a storage box is formed on a rear cover that covers the rear of a head pipe that supports a front fork. The lower part of the inner cover and the upper part of the leg shield are wrapped so that the leg shield is located on the rear side. The storage box is characterized in that the storage box is formed by fixing the leg shield except for its upper edge.

[0005]

[Function] According to the storage device according to the present invention, the rear cover is composed of the inner cover located on the handle cover side and the leg shield located on the footboard side, so that it is integrated from the footboard side to the handle cover side as in the conventional case. Each of them is smaller than the molded one, so the mold for resin molding them can also be small, reducing mold cost and reducing cooling time to improve manufacturing efficiency. Furthermore, since the vertical wrap portion between the inner cover and the leg shield is used as a storage box, the connecting portion between the two is not visible through the opening of the box, and deterioration in appearance can be avoided. Furthermore, since the present invention has a structure in which the lap portions of the inner cover and the leg shield are fixed to each other, compared to the conventional structure in which a bulge is formed in the middle of the rear cover and a large opening is formed in this portion. can improve rigidity.
