Abrégé
The purpose of the present invention is to provide an actuator that has a simple configuration and can stably achieve high output without the occurrence of magnetic saturation. This actuator has: a movable body provided with a turning shaft and a cylindrical magnet section having alternately N-pole faces and S-pole faces on the peripheral surface surrounding the turning shaft in the circumferential direction; and a fixed body provided with a bearing into which the turning shaft is inserted, pole tooth surfaces disposed facing the peripheral surface of a magnet section so as to surround the bearing in the circumferential direction, of the same number as the N-pole faces and the S-pole faces, and a coil that excites the pole tooth sections with polarities alternating in the circumferential direction by current being supplied. The movable body has as a turning reference position a position at which the center of the pole tooth surfaces in the circumferential direction and the switching position of the pole faces of the magnet section face each other, and is held to the fixed body so as to be turnable back and forth around the turning shaft in the circumferential direction. The bearing is a magnetic body.

Abrégé
Provided is an actuator that has a simple configuration and can stably achieve high output. This actuator has: a movable body provided with a cylindrical magnet section alternately having N-pole faces and S-pole faces on a peripheral surface thereof along the circumferential direction; a fixed body provided with pole tooth surfaces disposed facing the peripheral surface a magnet section in the circumferential direction, of the same number as the N-pole faces and the S-pole faces, and a coil that excites the pole tooth sections with polarities alternating in the circumferential direction by current being supplied; and a spring material that is connected to the freely movable body and the fixed body and holds the movable body to the fixed body in a freely movable manner. The spring material is fixed to at least one of the movable body and the fixed body via a joint section. The joint section has a fixing part for fixing and end section of the spring material, and a stress relaxation part that is disposed in proximity to the fixing part and relaxes stress generated during deformation of the spring material.
