Abstract

A rotary reciprocating drive actuator includes: a movable body (20) capable of reciprocating rotation around a shaft part (24) with a magnet (36) fixed to its outer periphery; and a unit main body (4) that causes the reciprocating rotation of the movable body (20) by interaction with the magnet (36). The unit main body (4) includes: a core body (K) including magnetic poles (412, 414) extending on one straight line on both sides of the magnet (36) in a radial direction of the shaft part (24), and a magnetic path part surrounding the magnetic poles (412, 414) and the magnet and connecting the magnetic poles (412, 414); coil bodies (45) wound around the magnetic poles (412, 414) and cause the interaction by energizing; and a biasing part (48) that is disposed in a recess (480) formed in the magnetic path part at a position between the magnetic poles (412, 414) in a circumferential direction of the shaft part (24), and biases the movable body (20) toward an initial position of the reciprocating rotation.
