摘要:
In a vibration wave motor having a vibration member and a movable member press-contacted to the vibration member so as to be rotatably driven thereby, the vibration member is supported by a plurality of elastic supporting arms and the elasticity of the supporting arms produces a frictional force between the vibration member and the movable member.
