摘要

A torsion spring (26) biases an opening link (22) from lock position to unlock position direction while biasing an opening lever (21) from actuated position to initial position direction. The opening lever moves from initial position to be actuated by the operation of the opening link arranged in vehicle door. A ratchet mechanism is detachably attached to a striker. A lift lever (23) operates the ratchet mechanism from engagement state with the striker to non-engaging state. A locking lever (24) moves between unlock position and locked position by operation of a key cylinder (38) arranged at vehicle door.
