PURPOSE: A vibration actuator is provided to improve vibration transmission efficiency compared to power consumption because vibration is directly transmitted to outside through a bearing. CONSTITUTION: A vibration actuator comprises a base(400), a stator(300) which is fixed to the base, and a vibrator(200) which faces the stator and rotates around a rotary shaft(230). The surface of the vibration, which faces the stator, is vertical to the rotary shaft. Vibration is generated as the vibrator is alternately rotated in forward and reverse directions by the electromagnetic force acting on the opposed surfaces of the stator and the vibrator.
