<p>PURPOSE:To provide size reduction by moving a rotating output member which is connected to a motor only between a lock position and an unlocking position. CONSTITUTION:When a motor 38 rotates in a normal direction, lock levers 11, 26 shift to a locking position, and when the motor 38 rotates reversely, the levers 11, 26 shift to an unlocking position. When the motor rotates in a normal direction again after it rotates in a normal direction and stops once, a connector 58 is switched to a super-lock condition. A rotating output member 44 is connected to the lever 11 through a lost-motion, and a spring 54 which energizes it in an unlocking rotational direction is fixed to the member 44. When the motor 38 is stopped after the member 44 is lock-rotated by the motor 38, the member 44 is rotated by the spring 54 in the unlocking direction by the amount of the lost motion. When the member 44 is rotated in the locking direction with the lever 11 kept in the locking position, the member 44 and the connector 58 are engaged with each other to keep the connector 58 in a super-locked condition. It is thus possible to reduce the size of a device.</p> |
