DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to a seat mounting structure for a motorcycle.

[0002]

2. Description of the Related Art A motorcycle is provided with a seat on which a driver sits. Some vehicles include seats for passengers other than the driver. In general, these sheets are arranged back and forth and are integrally formed (tandem seat specification).

On the other hand, there is a type in which a sheet is made detachable, a storage chamber is formed below the sheet, and the storage chamber is closed with the sheet. In this case, hooks are provided at the front lower portion of the seat, that is, at the lower portion of the driver's seat, so that the seat can be locked to the vehicle body side, and the seat lock is provided at the rear lower portion, that is, at the lower portion of the passenger seat, on the rear fender. A striker constituting the apparatus is provided so that the seat can be locked (locked).

By the way, since some users desire a single seat specification having only a driver's seat, a maker prepares a model in which a tandem seat is converted to a single seat on an assembly line. Answers user requests.

[0005]

However, the fact that the striker is located behind the hook and the striker behind,
It is necessary to move the striker when converting to a single seat. As a result, the cable length and layout of the seat lock device are changed, which leads to an increase in cost.

Further, since a striker is provided on the rear fender, it is necessary to form the upper surface of the rear fender in a planar shape. However, if the sheet is converted to a single sheet, the flat portion may be exposed to the outside and impair the appearance. Therefore, it is necessary to prepare a new rear fender for the single sheet, which also increases the cost.

SUMMARY OF THE INVENTION The present invention has been made in consideration of the above circumstances, and has as its object to provide a seat mounting structure for a motorcycle, which can share a seat lock device and a rear fender at the time of seat conversion.

[0008]

SUMMARY OF THE INVENTION A seat mounting structure for a motorcycle according to the present invention has the following features.
As described in claim 1, a motorcycle including a rear wheel behind the body frame, a rear fender above the rear wheel, and a seat arranged from a rear upper portion of the body frame to an upper portion of the rear fender,
A seat lock device is provided at a lower front portion of the seat, a locking portion for the motorcycle is provided at a lower rear surface of the seat, and a fender bracket is separately provided on the rear fender. And the load receiving portion of the seat is formed on the fender bracket.
