Patent ID: 7635166

Claim:
A controller for a seat locking device which locks a seatback, said controller comprising: a holder having an opening at a top end thereof; an operation knob which is rotatably provided in the opening of the holder, transmits an operating power to the seat locking device when a rotating operation is applied thereto, and is maintained to be lifted when the seat locking device is in an unlocked state, the operation knob being pivotally movable above a rotational axis thereof; an operating rod for connecting the controller to the seat locking device, and a support pin which is joined with an upper end of the operating rod and which is supported at a position between opposed side walls of the holder and spaced apart from the rotational axis of the operation knob, whereby pivotal movement of the operation knob about the rotational axis causes a corresponding movement of the operating rod; a protrusion which is integrally formed with the operation knob and rotates integrally with the operation knob around the rotational axis to show that the seat locking device is in an unlocked state when the operation knob is lifted; and a compensator which prevents gapping between a back face of the protrusion and a side wall of the holder facing the back face when the operation knob is lifted.
