ABSTRACT:
A latch device having a locking mechanism is locked and unlocked by a lock operating device comprising: a lock lever coupled to and operating the locking mechanism when driven to undergo displacement between terminal lock and unlock positions; a motor for driving the lock lever; a retaining member exerting an elastic force (1) to cause the lock lever to undergo the displacement with a click motion, over-riding an intermediate dead-center point against an elastic resistance and (2) to retain the lock lever positively in either terminal position after each displacement; and a retraction device for temporarily nullifying or greatly reducing the action of the retaining member at the time of the displacement of the lock lever.
