Abstract
A vibration actuator includes a vibrator, a contact body, at least one pair of first extensions, and at least one pair of second extensions. The vibrator includes a rectangular elastic body and an electromechanical energy transducer. The contact body comes into contact with the rectangular elastic body and the contact body and the vibrator move relative to each other due to vibration of the vibrator. The at least one pair of first extensions is disposed on each of two long sides of the rectangular elastic body, and protrudes in a direction intersecting a long-side direction of the rectangular elastic body. The at least one pair of second extensions is disposed on each of two short sides of the rectangular elastic body, and protrudes in a direction intersecting a short-side direction of the rectangular elastic body.
