(Effects of the Invention) As described above, the invention of claim 1 is provided with a case in which a box capable of storing a helmet is provided between a power unit suspended by a unit swing type suspension device and an operation seat, with the helmet top down. Provide a roughly bowl-shaped box body to accommodate,
Since the bottom of the box is integrally formed with a small-sized storage section that bulges wider and lower than the rear wheel between the pivot shaft and the rear wheel and that opens to the inside of the box, the shape of the box is utilized well. Thus, a space for accommodating small items can be sufficiently ensured, and the number of parts is reduced, so that the assemblability is improved.

Furthermore, since the accessory storage section is depressed near the bottom of the substantially bowl-shaped box, that is, near the top of the helmet, dust and the like entering the box easily fall into the storage section. Therefore, there is no possibility that dust entering the box body may damage the outer surface of the helmet. In addition, the storage section for accessories,
Since it is located between the pivot shaft and the rear wheel and bulges wider and downward than the rear wheel, it can have a function as a mudguard that prevents mud rolled up by the rear wheel from hitting near the pivot shaft.

According to the second aspect of the present invention, the battery housing is formed integrally with the bottom of the box so as to protrude downward toward the side of the rear wheel, so that the shape of the box can be used effectively and the number of parts can be reduced. It is possible to improve the assemblability with less. In addition, since the battery can be put in and out of the vehicle body from the storage portion, it is possible to perform maintenance such as charging of the battery without opening the operation seat as in the case where the battery is stored in the box. If the battery housing is provided on the same side as the transmission case of the power unit, the battery housing does not become an obstacle when the rear wheel is attached or detached, and the maintainability is further improved.
