Vibration actuator and optical apparatus
Abstract:
To reduce the length of the lens barrel, a vibration actuator has a vibrating element, a rotor, a pressing portion, a rotor holder that restricts a position of the rotor in the thrust and radial direction, and a bearing of which a rotation axis is coaxial with the axis of the vibrating element. The rotor holder includes an outer flange to receive the pressure force from the rotor portion, and an inner flange to serve as a first track face of the bearing.
