PROBLEM TO BE SOLVED: To provide a vibration actuator capable of preventing backlash of a magnet in a radial direction of a shaft.SOLUTION: In a vibration actuator 1, bearings 25, 26, which may slide relative to a shaft 20, are respectively provided at first and second weight parts 6, 7. Movement restriction parts 36, 37 restrict a magnet 4 from moving relative to the first and second weight parts 6, 7 in a radial direction of the shaft 20. Backlash of the magnet 4, which occurs in the radial direction of the shaft 20, is prevented by cooperation of the first and second weight parts 6, 7 which respectively have the bearings 25, 26. |
