An ultrasonic motor, characterized in that a biasing means for biasing the rotor toward the torsional vibrator is incorporated in the recess. The brief description of the drawing has been amended as follows. "Bearing" in line 1 on page 11 of the specification is corrected to "hollow bolt."

Claims

[Scope of utility model registration request]

a torsional oscillator rotatably supported by a bearing; a longitudinal oscillator disposed close to and opposite to the torsional oscillator; a connecting member connected to the child; a rotor rotatably disposed on the connecting member and positioned between the torsional oscillator and the longitudinal oscillator; and a rotor attached to the other end of the connecting member and configured to rotate a pressure spring that presses and contacts the mutually opposing motion transmission surfaces of the vibrator and the vertical vibrator with the rotor; a spring housing recess is provided in the motion transmission surface of the vertical vibrator; An ultrasonic motor characterized by incorporating a biasing means for biasing a rotor toward a torsional vibrator.
