POSITION HOLDING DEVICE FOR ROTATING LEVER AND VEHICLE DOOR LOCK DEVICE PROVIDED WITH SAID POSITION HOLDING DEVICE FOR ROTATING LEVER

Title:

POSITION HOLDING DEVICE FOR ROTATING LEVER AND VEHICLE DOOR LOCK DEVICE PROVIDED WITH SAID POSITION HOLDING DEVICE FOR ROTATING LEVER

Document Type and Number:

WIPO Patent Application WO/2012/144413

Kind Code:

A1

Abstract:

This position holding device that is for a rotating lever is provided with a rotating lever and a torsion spring, and can elastically hold the rotating lever at the two positions of a first position and a second position. The torsion spring has: a wound section; and a first arm section and second arm section that extend from the wound section and face each other sandwiching the engagement section of the rotation lever. In the first arm section, a thread is formed at the intermediate portion thereof. An energizing section is formed in the second arm section. As a result, the energizing force of the energizing section can be caused to act on the rotating lever as a braking force resisting the energizing force by the thread. Consequently, it is possible to reduce the sound of contact when the rotating lever contacts a stopper member.
