发明名称 VIBRATION ACTUATOR
摘要 PROBLEM TO BE SOLVED: To provide a vibration actuator which allows for enhancement of assembly accuracy while facilitating the assembly.SOLUTION: A vibration actuator 100 comprises: a stator 12; a rotor 20 arranged in contact with the stator 12; a frame member 24 supporting the rotating shaft 22 of the rotor 20 rotatably and having a bearing hole 24a1 through which the rotor 20 can be inserted; a piezoelectric element 13 arranged in contact with the stator 12 and generating supersonic vibration, and generating vibration for rotating the rotor 20 on the contact surface 12a1 of the stator 12 with the rotor 20; and a coupling rod 31 and a disc spring 34 for pressing the rotor 20 against the contact surface 12a1 of the stator 12 by being coupled with the frame member 24 and energizing the frame member 24 toward the stator 12.
