Vibration driven actuator, apparatus, and optical apparatus
Abstract:
A vibration driven actuator includes a vibrator, a vibrator holder, a friction member, a pressing member that enables the vibrator to compressively contact the friction member in a first direction, and a pressure transmitting member disposed between the vibrator and the pressing member. The vibrator and the friction member relative move in a second direction orthogonal to the first direction due to the vibration. A first contact portion disposed to one of the vibrator holder and the pressure transmitting member contacts a second contact portion disposed to the other of the vibrator holder and the pressure transmitting member so as to restrict a relative displacement between the vibrator holder and the pressure transmitting member in the second direction, and to allow a relative rotation between the vibrator holder and the pressure transmitting member on a plane parallel to the first direction and the second direction.
