Abstract:
A vibration actuator includes a fixing body including a base part, and a magnetic suction force generation part provided at a core on which a coil is wound; a movable body including a connecting part, and a suction part suctioned by the magnetic suction force generation part through energization to the coil; and a plurality of elastic support parts. The suction part is disposed in a vicinity of a magnetic pole of the core of the magnetic suction force generation part with an air gap between the suction part and the magnetic pole in a vibration direction, and the suction part is disposed at a center portion in the vibration direction of the movable body supported by the plurality of elastic support parts.
