Lock cylinder maintaining structure for bestride type vehicle and method thereof

Abstract

PROBLEM TO BE SOLVED: To perform smooth key operation and prevent the occurrence of mischievous action by suppressing a key cylinder from falling, in a key cylinder holding structure and method for a saddle-riding type vehicle.SOLUTION: In a key section 34 of a key cylinder 31, an engage groove 35 is formed which is exposed inside of a stay while notching the key section in a circumferential direction of the cylinder and abutting a flange 33 to an outer side surface 42e of a supporting plate 42. To the engage groove 35, an inner edge part 54 can be engaged which is externally fitted to the key cylinder 31 and avoids a washer opening part in a washer member 51 abutted to an inner side surface 42f of the supporting plate 42. The supporting plate 42 is held between the washer member 51 and the flange 33.

Description

technical field [0001] The present invention relates to a key cylinder holding structure and method for straddle-type vehicles such as motorcycles. Background technique [0002] Conventionally, there is known a key cylinder holding structure of a straddle-type vehicle (for example, refer to Patent Document 1), and the straddle-type vehicle has a seat for locking, for example, a straddle seat in the straddle-type vehicle. A seat locking device; a key cylinder that mechanically operates the seat locking device via a connection mechanism such as a cable, a rod, etc. so as to be able to release the above-mentioned lock; supporting item. [0003] Patent Document 1: Japanese Patent Laid-Open No. 2010-36596 [0004] In the prior art mentioned above, the lock cylinder is inserted into the insertion hole of the support member, and a U-shaped leaf spring is mounted on the outer periphery of the lock cylinder protruding inwardly of the support member. However, in this case, there is...

AI Technical Summary

Problems solved by technology

[0004] In the prior art described above, the lock cylinder is inserted into the insertion hole of the support member, and a U-shaped leaf spring is mounted on the outer periphery of the lock cylinder protruding inwardly of the support member. The elastic locking state is maintained on the support, but in this case, there is a tendency for the lock cylinder to fall easily (easy to tilt) relative to the support.

[0005] For example, if the lock cylinder falls due to the reaction force of the unlocking operation of the seat lock device, the seat lock device needs to be operated with a stroke (lever ratio) corresponding to the fall, and the key operation becomes heavy.

In addition, in order to suppress the occurrence of mischief, it is necessary to take countermeasures such as covering the inside of the support with a cover or the like so as not to touch the lock cylinder, which will increase the number of parts.
