摘要:
The present invention relates to a vibration type actuator or a vibration type driving apparatus that includes a vibration member that generates therein respective vibration displacements in at least three different directions, and a plurality of contact members contacting the vibration member, wherein the respective vibration displacements in the three different directions generate a composite vibration that simultaneously moves selected contact members of the plurality of contact members relative to the vibration member.
