The helmet 34 can be easily taken in and taken out through the opening 15a of the helmet storage box 15 by unlocking the seat 12 and opening the seat 12 using the hinge 31 as a fulcrum. In addition, the front wall 15b of the helmet storage box 15 that projects upward from the step floor 3 is
Even when the legs of a seated rider are located at the rearmost part of the step floor 3, there is a dead space where they do not come into contact with the lower leg shins, and do not interfere with freedom of riding posture.

On the other hand, the cover plate 32 not only guides the helmet 34 stored in the helmet storage box 15 with its protrusion 32a as described above, but also covers the head of the engine 23 when the power unit 20 swings up and down. It is accommodated in the protrusion 32a of the plate 32 and allows the engine 23 to swing.

In this embodiment, the front wall of the helmet storage box has been described as having a double wall structure consisting of a rear cover and an inner lining, but the front wall of the present invention can also be formed of only the rear cover.

Additionally, the fuel tank may be stored and arranged in the front part of the helmet storage box. In this case, the tank volume can be gained within the front wall, so the front and rear length of the fuel tank can be shortened. The rear helmet storage space can be expanded.

〔Effect of the invention〕

As described above, the present invention includes a helmet storage box disposed inside a rear body, and a seat whose front end is pivotally supported on the upper part of the rear body to open and close toward the front of the vehicle body, and a seat that covers the helmet storage box. The power unit, which integrates the engine and the transmission mechanism, is placed below the helmet storage box so that it can swing vertically, ensuring a swing space for the power unit between the power unit and the helmet storage box. , a helmet storage box with few people can be provided.

In addition, a wide opening that covers the entire passenger seat area of the seat is provided at the top of the helmet storage box, which not only makes it easy to put in and take out the helmet, but also allows the seat to cover the opening of the helmet storage box. The seat is sized to cover the seat and is supported on the outside of the opening, so vibrations caused by the car and shocks from the road surface are absorbed by the elastic force of the seat, providing a comfortable ride even with the same cushion thickness as before. Furthermore, since the seat height can be kept low, the rider's footing is also good.

Furthermore, the shape of the rear body can be changed by installing a fuel tank close to the helmet storage box inside the rear body behind the helmet storage box, and extending this fuel tank into the rear cowl that forms the rear wall of the rear body. By making effective use of the dead space within the rear cowl, the fuel tank container can be secured at the rear of the rear body, and the volume of the helmet storage box can also be expanded to the rear.
