Oscillatory actuator

An oscillatory actuator comprising:

• a cylindrical case;
• an electromagnetic driver provided inside the case;
• a mover enabled to oscillate through driving by the electromagnetic driver;
• a plate spring having a plurality of arms supporting the mover inside the case;
• and
• an inner guide that is provided inside the case, has a part contactable with the plate spring after movement of the plate spring beyond a predetermined range, and is configured to restrict movement of the plate spring beyond the predetermined range, the inner guide being located further toward a center of the case than the plate spring in a direction of an oscillation axis of the mover;
• wherein the part of the inner guide that is contactable with the plate spring is located between the electromagnetic driver and the plate spring in the direction of the oscillation axis of the mover.
