Abstract
A vibration driven motor or actuator includes a vibrating member for generating a vibration therein in response to an electrical signal applied thereto, and a contact member frictionally engaged with the vibrating member to be driven by the vibration. The contact member has a structure for causing sin and cos modes of the vibration generated in the contact member to have different natural frequencies when the contact member is driven by the vibration.
