<p>A three-stable oscillating electromagnetic actuator (101) includes a cylindrical stator (45) from which a plurality of first magnetic poles (45b) project toward a center direction, a mover (1) that extends in a circumferential direction inside the stator and is reciprocatingly and rotatably supported along the circumference, and a plurality of coils (47A to 47F) that are wound around the first magnetic poles and bias the mover to cause it to stop in three positions, which are a first stable position that is on one end side of a rotation range of the mover, a second stable position that is on the other end side, and a neutral position that is an intermediate position, wherein the three-stable oscillating electromagnetic actuator further includes a second magnetic pole (21a, 21b) made of a magnetic material that abuts against a rotation-direction end of the mover to stop the mover in the first stable position and the second stable position.</p> |
