Description

Description: TECHNICAL FIELD The present invention relates to a scooter-type vehicle provided with a large box that can accommodate large luggage such as a helmet below a driving seat.

BACKGROUND OF THE INVENTION There is a two- or three-wheeled scooter type vehicle in which a large box is provided below a driver's seat so that a driver's helmet can be stored in the box. This type of vehicle requires a handle for lifting the vehicle body when hanging the main stand, that is, a handle for hanging the stand. Conventionally, this handle is generally fixed to the frame of the vehicle body. In this case, however, a hole for passing the handle must be formed in a box or a rear cover that covers the side of the power unit. For this reason, there arises a problem that the mounting structure of the handle becomes complicated. It is conceivable to provide this handle on the box, but in this case also, a hole must be provided in the rear cover, and the same problem occurs.

Also, if the handle is fixed to the frame or box located inside the car body and the handle is to be placed at the ideal position for operation, the handle will extend greatly from the frame in the width direction of the car body, and the handle will be If it protrudes in the width direction, it becomes cantilevered, which is disadvantageous not only in strength but also causes an increase in weight.

In particular, when the helmet can be stored in a large box, the opening of the box needs to be sufficiently large. However, if the body frame is arranged near the side edge of the box and the handle is fixed thereto, the opening width of the box is limited by the handle and the body frame supporting the handle. For this reason, it becomes difficult to increase the opening width of the box.

(Object of the Invention) The present invention has been made in view of such circumstances,
When using a scooter-type vehicle with a large box for storing large luggage such as a helmet below the driver's seat, it is not necessary to make a hole in the rear cover when a handle for stand is provided. Simplicity and good operability, providing a large opening width of the box, enabling storage of large helmets and other large luggage, and providing a scooter-type vehicle that is suitable for reducing the weight of the body without the need for large brackets etc. The purpose is to do.

If the right foot is stepped down and the handle 110 is pulled up at the same time, the stand 116 rotates clockwise in FIG. 1 and stabilizes in the upright position. At this time, when an upward force is applied to the handle 110, the force is transmitted to the lock device 82 via the seat bottom plate 72 and the hook 84, and further transmitted to the frame 10 via the box 50.

(Effects of the Invention) As described above, the present invention provides a case in which a large box body for storing large luggage such as a helmet is provided below a driver's seat. The rear part can be locked to the vehicle body side, and a bulge part bulging outward and opening downward is formed at least at the rear part of at least one side wall of the seat bottom plate. As described above, since the handle for hanging the stand extending outward is attached to the seat bottom plate, there is no need to make a hole for passing the handle through the rear cover, and the structure is simplified. Further, since the seat bottom plate is bulged outward, a sufficiently large opening width of the box body can be secured, and an opening width capable of accommodating a large helmet can be obtained. As described above, since the opening width of the box is not affected by the position of the handle, the degree of freedom in setting the position of the handle is increased.

Further, the bulging portion can be easily visually observed from the outside, and the handle is located substantially along the lower edge of the bulging portion, so that the operability of the handle is good. Since this handle can also be used for opening and closing the driving seat, there is no need to separately provide a handle for opening and closing the driving seat, and the structure is simplified.

Furthermore, since the handle is separated from the opening of the box when the driver's seat is opened, the handle does not hinder the loading / unloading of the load and the operability is good.

Furthermore, since the driver's seat lock is located at the rear of the driver's seat and the handle is also at the rear of the side edge of the driver's seat and the handle is close to the lock, it is added to the handle despite its simple structure. A large operating force can be transmitted to the vehicle body frame via the lock.
In this way, the handle is attached to the seat bottom plate, and it is arranged along the vicinity of the lower edge of the bulging part, so the handle is small, the structure is simple, special brackets are unnecessary or small, and the body Weight reduction becomes possible.
