Further, the key cylinder 80 can be arranged close to the lock member 77, and the wiring of the operation cable can be simplified. Further, since the duct opening 60 is covered with the duct cover 63 and the insertion hole 80c of the key cylinder 80 is located inside the duct opening 60, the appearance can be improved and the mischief and the like can be more reliably performed. It can be prevented.

According to the wheel lock member storage structure of this embodiment, by removing the main seat 7, the lock member 91 can be taken in and out from the front end opening of the storage space in the front-rear direction, so that it is not necessary to remove the tandem seat 8. Therefore, when luggage is loaded on the tandem seat 8,
The lock member 91 can be stored and taken out with the luggage as it is. Further, since the clip 98 supporting the U-turn portion 91b is located at the front end opening of the lock member accommodation space 31, the U-turn portion 91b can be easily held.

Further, since the support piece 96 for supporting the lower surface of the lock member 91 and the pressing piece 97 for pressing the upper surface are integrally formed on the bottom plate 71 of the tandem seat 8, the empty space under the seat can be effectively utilized for storage. As compared with the conventional case where the rear fender is stored at the bottom, the storage space can be prevented from being reduced, damage to other stored items can be avoided, and the strength requirement of the rear fender can be relaxed. Further, since it is not necessary to hold the lock member by another component, the cost can be reduced.

Further, since the main seat 7 and the tandem seat 8 are simultaneously locked by the single seat lock device 75, the lock structure can be simplified and the cost can be reduced, and the storage space can be provided below both seats 7 and 8. Can be secured.

In the above-mentioned storage structure, the supporting piece 96
It was formed in the shape of a letter and cut and raised the pressing piece 97,
The lock member holding structure of the present invention is not limited to this. For example, as shown in FIGS.
A slit 96a may be formed in the lower portion of the lock member 6 and the lock member 91 may be fitted from below. Alternatively, an arcuate pressing piece 97a may be formed to apply downward biasing force to the pressing member 97a. You may do it.
