PURPOSE:To release a rotor and stator from a state of pressurized contact with each other with a simple structure by releasing the first and second members from a state of pressurized contact with each other by actuating a pressurizing force releasing means. CONSTITUTION:A rotor 5 and stator 1 are released from a state of pressurized contact with each other by pushing the shaft section 4a constituting the output shaft of this oscillatory-wave motor protruding from the front face of a device main body, namely, to a frame 9 side to the rear face side of the device main body (frame 8 side) against the force of a compression spring 12. A pressurized contact releasing mechanism is constituted of a cylindrical fixture 15 with a screw section on the outer peripheral surface and a bottomed knob 14 with an inside screw section which is engaged with the screw section on the fixture 15 and the fixture 15 is fixed to the frame 9 with screws 18 so as to surround the shaft section 4a. A steel ball 17 is fitted to the inner surface of the bottom of the knob 14 by means of a cap 16 so that the ball 17 can face the end face of the shaft section 4a. |
