Patent ID: 8796906

Claim:
A piezoelectric motor in which stretching vibration and bending vibration are generated in a vibrating body to move an object, the piezoelectric motor comprising: a vibrating body which contains a piezoelectric material, and has a convex portion protruding from an end surface; a case which accommodates the vibrating body; a pressing elastic body which presses the case in a direction bringing the convex portion of the vibrating body into contact with the object; buffer portions which sandwich both sides of the vibrating body from a direction intersecting a bending direction of the vibrating body in the case, and contain a material having dynamic viscoelasticity; pressing lids which are attached to the case; disk springs which are provided between the pressing lids and the buffer portions, and are compressed by the pressing lids; and pressing plates which are provided between the buffer portions and the disk springs to restrict movement in a stretching direction and a bending direction of the vibrating body.
