AI Technical Summary

Technical Problem

Existing handle lock mechanisms may accidentally unlock after wear, reducing the vehicle's anti-theft capabilities.

Method used

A rotation limiting part is introduced into the handle locking device to limit the rotation of the connector and ensure that the locking member is not accidentally released when it is in the locked state. This is achieved by limiting the rotation of the connector when the operated member is in the locked position.

Benefits of technology

It effectively prevents accidental release of the handle lock, thus improving the vehicle's anti-theft capabilities.

Abstract

The present invention suppresses unexpected unlocking and improves the anti-theft performance of a vehicle. A handle lock device (20) is provided with: a rotatable operation knob (26); a joint (27) that rotates integrally with the operation knob (26); a contact holder (32) that can rotate integrally with the joint (27); a positioning mechanism (33) for positioning the contact holder (32); a lock member (38) that moves to the engagement position via the joint (27) by the rotation operation of the operation knob (26); and a coil spring (41) that urges the lock member (38) toward the non-engaged position. A rotation restricting portion (27d, 40g) is provided between the joint (27) and the lock member (38), and the rotation restricting portion (27d, 40g) restricts rotation of the joint (27) when the operation knob (26) is in the lock position (22c).
