Lock cylinder maintaining structure for bestride type vehicle and method thereof

Abstract

The present invention relates to a lock cylinder maintaining structure for bestride type vehicle and a method thereof, being able to restrain toppling of the lock cylinder so as to perform smooth key operation and to restrain occurence of tricks. A clamping groove (35) is formed on a key part (34) of a lock cylinder (31); the key part (34) is cut along the circumferential direction of the lock cylinder body to form the clamping groove (35); the clamping groove (35) exposed toward the inside of a supporting piece when a flange part (33) is propped to the outer side surface of a supporting plate (42); an inner peripheral part (54) can be clamped on the clamping groove (35), and is embedded on the lock cylinder (31) and avoids the gasket opening part on a gasket component (51) which is propped to the inner side surface (42f) of the supporting plate (42); and the supporting plate (42) is clamped through the gasket component (51) and the flange part (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.
