An oscillatory actuator 1 includes a cylindrical case 2, an electromagnetic driver 3, a mover 4, a first damper 40a, and an inner guide 6a. The electromagnetic driver 3 is provided inside the case 2. The mover 4 is enabled to oscillate through driving by the electromagnetic driver 3. The first damper 40a has a plurality of arms 52a supporting the mover 4 from an inner surface of the case 2. The inner guide 6a is provided on the inner surface of the case 2 and restricts movement of the first damper 40a beyond a predetermined range. The inner guide 6a is located further toward a center of the case 2 than the first damper 40a in a direction of an oscillation axis ◯ of the mover 4.
