    Abstract: This actuator has a stationary body having either a coil or a magnet, a movable body having the other, that is, a magnet or a coil, and an elastic body that supports the movable body so as to be capable of moving with respect to the stationary body. The movable body moves reciprocally with respect to the stationary body in the vibration direction due to concerted movement of the magnet and the energized coil. The magnet can advance into and separate from the interior of the coil in the vibration direction. The elastic body is a plate-shaped elastic body one end of which is secured to a stationary unit, the other end of which is secured to the movable body, and which supports the movable body with a cantilever structure so as to be capable of oscillating reciprocally in the vibration direction.
