ABSTRACT:
A piezoelectric motor includes: a base; first and second piezoelectric elements that are provided symmetrically on the base to face with each other, the first and second piezoelectric elements actuating in opposite directions; first and second displacement enlarging mechanisms that respectively enlarge actuating displacements of the first and second piezoelectric elements through first and second levers that rotate around first and second fulcrums fixed to the base; first and second leaf springs that are respectively coupled to action points of the first and second levers at one ends thereof; and an actuating portion that is coupled to the other ends of the first and second leaf springs and swings in accordance with actuation of the first and the second piezoelectric elements, the actuating portion being urged against a driven member to actuate the driven member with a frictional force.
