A vibration actuator includes a vibrator including an electromechanical transducer and an elastic body, a vibrator fixing member configured to hold the vibrator, a driven member configured to come into frictional contact with the vibrator so as to move relative to the vibrator, a pressing portion configured to press the vibrator against the driven member, a guide portion configured to guide the vibrator in a direction in which the vibrator moves, and a vibration damping member disposed between the vibrator fixing member and the movable plate. The guide portion includes a movable plate configured to move integrally with the vibrator, a rolling member configured to roll in the direction in which the vibrator moves, and a press-and-hold member configured to press the rolling member against the movable plate. |
