Claims

[Claims for Utility Model Registration] In an actuator in which an object to be operated is reciprocated by a drive motor, a rotary cam member having a gear that is rotated in forward and reverse directions by the drive motor is pivotally supported in a housing, and the rotary cam member is The gear is constructed by erecting spiral walls whose top surfaces vary in height in the axial direction from both side surfaces of the gear, and between the end surfaces in the rotational direction of the ends on the side where the top surfaces of both the spiral walls are the highest. are arranged with a gap in the circumferential direction, the output member is supported by the housing so as to be movable in the axial direction of the rotary cam member, and an engagement protrusion is positioned between the two spiral walls and slidably contacts the top surface. The actuator is characterized in that the output member is provided with a portion, and the engagement protrusion is set to have a width that allows it to move in the axial direction within a gap between the end faces of the spiral wall in the rotational direction.
