Abstract
A piezoelectric motor has a vibrating body for undergoing vibrational movement in accordance with a vibration wave, a contact member disposed in contact with and driven by the vibrating body during vibration thereof, and a support member for supporting the vibrating body in the vicinity of a vibration node of the vibration wave. A pressurization member applies pressure to the support member along a pressurization axis to maintain the vibrating body in pressure contact with the contact member so that during vibration of the vibrating body, the support member regulates movement of the vibrating body in a direction of rotation about the pressurization axis.
