SUMMARY OF THE INVENTION
In the case of a structure in which an intermediate portion of the rear cover is bulged rearward to serve as a rear wall of the storage box, the rear cover is necessarily a large part from the footboard to the vicinity of the handle cover. Therefore, the size of the resin molding die of the rear cover becomes large, and the cost of the die itself increases, and there is a problem that a long time is required for cooling at the time of the resin molding, which becomes a bottleneck in improving 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 a problem that the appearance of the storage box portion is deteriorated. Further, in the case of the above-mentioned conventional structure, since the large opening is formed in the rear bulging portion of the rear cover, there is a problem that the rigidity of the rear cover itself tends to decrease. The present invention has been made in view of the above-mentioned conventional circumstances. By reducing the size of a resin molding die, it is possible to reduce the cost of the die, shorten the cooling time, improve the production efficiency, and reduce the appearance. It is an object of the present invention to provide a storage device for a scooter-type motorcycle which can avoid the problem and improve the rigidity.

[0004]

According to the present invention, a head pipe for supporting a front fork is surrounded by a front cover and a rear cover which are divided into two front and rear parts, and a storage box is formed in the rear cover. In the storage device for a scooter-type motorcycle, the rear cover has a vertically divided structure of an inner cover located on an upper side and a leg shield located on a lower side, and a lower part of the inner cover and an upper part of the leg shield are formed by legs. The storage box is formed by wrapping the shield so that the shield is located on the rear side, and fixing the portions of the wrap portion except for the upper edge of the leg shield, and forming the front cover near the upper edge of the leg shield. The upper cover and the lower cover are divided into two parts, and the lower cover is formed by connecting the left and right walls with the front wall to form a substantially U-shape in plan view. With the, to the lower cover,
Forming a ceiling wall connecting the upper edges of the left and right walls,
The lower cover and the side edges of the leg shield are connected to each other.

[0005]

According to the storage device of the present invention, the rear cover is constituted by the inner cover located on the handle cover side and the leg shield located on the foot board side, so that the rear cover is integrated from the conventional foot board side to the handle cover side. Each of them is smaller in size than the formed one, so that the mold for forming the resin is also small, so that the mold cost can be reduced and the cooling time can be shortened to improve the production efficiency. Further, since the vertical wrap portion between the inner cover and the leg shield is used as the storage box, the connection portion between the two is not visible from the opening of the box, so that the appearance can be prevented from deteriorating. Furthermore, since the present invention has a structure in which the wrap portions of the inner cover and the leg shield are fixed to each other, the conventional structure in which a bulging portion is formed in the middle of the rear cover and a large opening is formed in the portion. Rigidity can be improved in comparison. The upper and lower walls are substantially U-shaped in plan view, and the left and right walls are connected by a ceiling wall, and the side edges of the lower rigid cover itself are connected to the side edges of a leg shield constituting a part of the storage box. Therefore, the rigidity of the lower cover is increased at the same time as the rigidity of the storage box portion is increased, and the center of the lower cover in the vehicle width direction does not deviate from the center of the vehicle body, so that the appearance can be improved.
