Abstract
A vibration type actuator including a vibrator configured to vibrate due to a driving voltage, a slider configured to come into friction contact with the vibrator, a pressing plate for pressing the vibrator on the slider, a base to which the vibrator is fixed, a holding member configured to hold the base, and a coupling unit is provided. The vibration type actuator couples the vibrator and the holding member without backlash in a relative movement direction of the vibrator and the slider due to vibrations of the vibrator and freely moves the base with respect to the holding member in a direction of pressure of the pressing plate.
