PURPOSE:To simplify the structure, to reduce the size and the cost of a piezoelectric motor by generating longitudinal and lateral vibrations of the same wavelength at an elastic rod of a stator by a piezoelectric element, and moving a moving unit mounted on the side. CONSTITUTION:A planer piezoelectric element 2 is bonded to the end of a square rod 1 of an elastic member of a metal, a platelike piezoelectric element 3 is bonded to the bottom of the rod, thereby constructing a stator. A moving unit 4 is mounted on the upper surface of the rod 1, and a stator is mounted on a stationary base 5. Longitudinal and lateral vibrations of the same wavelength are generated at the rod 1 by the elements 2, 3 to move the unit 4. |
