る圧電モータ。[Claims for Utility Model Registration] A piezoelectric element that performs longitudinal vibration; a resonator that is in contact with the piezoelectric element and resonates with the longitudinal vibration; A disk that contacts the resonator at two places and has bending vibration pieces protruding from the other surface, and a rotor that comes into contact with the bending vibration pieces and rotates upon receiving the transmission of the bending vibration. In the piezoelectric motor, the bending vibrating piece is composed of a plurality of protrusions having a length equal to or less than the approximate radius of the disk, and each of the protrusions is displaced from a node where deflection due to bending vibration generated in the disk is minimal. A piezoelectric motor characterized by being arranged as follows.
