SOLUTION: This actuator comprises: the housing: a rotary member 84 for rotating two cam protrusion pieces 84a and 84b rotatably held in the housing; a motor for rotatively driving the rotary member; and the actuation lever 85, the one end of which is oscillatably held in the housing, and which is engaged with the cam protrusion piece and oscillated to put the door lock device into a locked or unlocked state. The actuation lever is equipped with: an arm portion 851 which is coaxial with an oscillating shaft 82 erected on a facing surface 851b facing the rotary member and which has a guide hole 851a allowing the insertion of a rotating shaft 88 of the rotary member; and a protrusion 852 which is provided with a stopper wall 852a provided on the leading end side of the arm portion, abutting on one 84a of the cam protrusion pieces and regulating its rotation, and an oscillating recessed groove 852b for undergoing the fit-in and abutment of the other one 84b of the cam protrusion pieces and oscillating the actuation lever. The protrusion is protruded toward the rotary member from the facing surface. COPYRIGHT: (C)2009,JPO&INPIT
