Vibration type actuator and vibration type driving apparatus

摘要

A vibration type actuator comprises a vibration member for generating vibration displacements in at least three different directions and a contact member in contact with the vibration member. In the actuator the vibration displacements in at least three different directions are excited in the vibration member to generate synthetic vibrations and provide the vibration member and contact member with a relative motion in a desired direction.
