摘要：Provided is a vibration actuator comprising an elastic body; an

electromechanical transducer that causes the elastic body to vibrate; and a rotating body

that rotates in response to a drive force received from contact with the elastic body at avibrational antinode thereof, wherein the rotating body contacts the elastic body at aprescribed position along a direction in which an axis of the rotation extends. In thevibration actuator, the elastic body includes an elastic body contact member that isarranged in a region that includes the vibrational antinode of the elastic body, therotating body includes a rotating body contact member that receives a drive force bycontacting the elastic body contact member, and one of the elastic body contactmember and the rotating body contact member has a contact surface that is orienteddiagonally to the axis of rotation and contacts the other of the elastic body contactmember and the rotating body contact member.
