Description

Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a seat mounting structure for a motorcycle. 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, a hook is provided at a lower front portion of the seat, that is, a lower portion of the driver's seat to enable the seat to be locked to the vehicle body, and a seat lock is provided at a lower rear portion of the seat, that is, a lower portion of the passenger seat, on the rear fender. A striker constituting the apparatus is provided to enable locking (locking) of the seat. [0004] 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, since the hook is located in front and the striker is located behind,
When converting to a single seat, it is necessary to move the striker. As a result, the cable length and the layout of the seat lock device are changed, which leads to an increase in cost. Further, since the 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 the appearance may be impaired. Therefore, it is necessary to prepare a new rear fender for the single sheet, which again causes a cost increase. 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] A seat mounting structure for a motorcycle according to the present invention is designed to solve the above-mentioned problems.
