PROBLEM TO BE SOLVED: To provide a vibration actuator capable of changing a vibration direction by a simple structure.SOLUTION: A vibration actuator comprises: a rotation motor 10 in which positive and reverse rotation movements are controlled; an eccentric rotor 20 in which a center of gravity is eccentrically fixed to a rotational axis 11 of the rotation motor 10 and that rotates and moves with the rotation of the rotation motor 10; a housing 30 that fixes and houses the rotation motor 10; and a stopper 40 as positioning means for determining an initial position of the eccentric rotor 20 to the housing 30. According to the initial position of the eccentric rotor 20 determined by the stopper 40, the housing 30 (rotation motor 10) is vibrated in a specific direction by a reciprocally rotational motion of a minute angle of the rotation motor 10.SELECTED DRAWING: Figure 1 |
