VIBRATION DRIVEN ACTUATOR

摘要

A vibration driven motor comprises a bar-shaped elastic member and a piezo-electric element for causing a plurality of bending mode vibrations having a predetermined phase difference therebetween in a plurality of planes of the elastic member in order to drive a movable body by a rotary motion caused in particles of the elastic member. A support member which extends along an axial center of the bar-shaped elastic member is provided at one end or each end of the elastic member.
