Abstract
A rotary reciprocating drive actuator reciprocally and rotationally driving the movable body about the shaft part in relation to the fixed body by the electromagnetic mutual effect of the coil and the movable magnet, wherein the movable magnet is magnetized in the radial direction of the shaft part, the two magnetic poles are disposed facing each other across an air gap in the radial direction of the movable magnet and the shaft part, and the fixed body has a rotation-angle-holding part disposed facing the movable magnet across the air gap, the rotation-angle-holding part holding the rotation angle position of the movable magnet by the magnetic attraction force generated with the movable magnet.
