A lock pin is held by the base plate and movable between locking and unlocking positions. A compression spring is disposed about the lock pin to bias the same toward the locking position. A lock plate is secured to a fixed member such a wall of a vehicle body. The lock plate has a plurality of lined lock holes with which the lock pin is engageable when assuming the locking position and a guide slot which extends along the lined lock holes. A lift plate is pivotally held by the base plate. The lift plate lifts the lock pin to the unlocking position when pivoted to a lift position from a rest position. A lift lever is pivotally held by the base plate. The lift lever has a first arm portion which contacts the lift plate and a second arm portion which enters the guide slot. The lift lever pivots the lift plate to the lift position when pivoted to a lift position from a rest position. A coil spring is employed for biasing both the lift plate and the lift lever to assume their respective rest positions.
