する圧電モータ。 A rotor is provided at the other end of the torsional oscillator with one end fixed and rotatable coaxially with the torsional oscillator, and a piezoelectric actuator that expands and contracts in the axial direction of the torsional oscillator is provided between opposing surfaces of the torsional oscillator and the rotor. In the piezoelectric motor, which rotates the rotor by intermittently transmitting the torsional vibration of the torsional oscillator to the rotor through contact with the piezoelectric actuator, the piezoelectric actuator has its tip protruding from one of the opposing surfaces of the torsional oscillator or the rotor. A piezoelectric motor characterized by being buried in the ground.
