摘要: Disclosed is an actuator that realizes reciprocal rotational motion of an electric toothbrush, for example, without utilizing a drive transmission mechanism that is separate from the drive source. In the actuator, a fixed body (120) has a coil (128) that is disposed around a magnet (160) and faces the magnetic planes with different polarities within the magnet (160) at individual prescribed distances, and an outer yoke (150) that covers the outer periphery of the coil (128). The fixed body (120) rotatably supports a movable body (110), which holds the magnet (160), via a coil spring that is an elastic member (130) made from a wire. An alternating current supplying part (140) supplies an alternating current having roughly the same resonance frequency as that of the fixed body (120) to the coil (128) to cause the movable body (110) to vibrate in a reciprocal rotational motion. The coil spring that is the elastic member (130) uniformly disperses stress generated by the vibration.

摘要: A vibration generator 1 has an attachment structure of a spring by which the attachment error of the spring elastically supporting a mover composed of a magnet and a yoke does not become the error of the span of the spring to make it possible to improve the ease and yield of manufacture. The vibration generator 1 includes a mover which is composed of a magnet 5 and yokes 4, 7a and 7b, and a spring 6 which is composed of an integrally molded article made of an elastomeric material and elastically supports the mover to allow the mover to vibrate in the central axis direction C. The spring is arranged on the outside of a coil 3 in a radial direction thereof and extends along the radial direction. An outer end portion 6a in the radial direction is nipped by two parts 2 and 8 in the central axis direction to be fixed to the housings 2 and 8, and an inner end portion 6b in the radial direction is nipped by two parts 7a and 7b constituting the outer circumferential part of the yoke in the central axis direction to be fixed to the outer circumferential part of the yoke. The outer end portion and the inner end portion have projecting parts formed to project from an elastic deformation section 6c, connecting the outer end portion and the inner end portion to each other, into two directions along the central axis.
