摘要：
Provided is a vibration actuator comprising a drive unit that generates a drive force; a vibrating component that vibrates according to the drive force from the drive unit; a rotating body that receives the vibration of the vibrating component to rotate; and a converting section that changes a contact force between the vibrating component and the rotating body according to size of a load acting on the rotating body.
