Abstract:
1. A drive unit, comprising: a shaft; a movable body supported by the shaft so as to be displaceable along the shaft; a vibratory actuator configured to drive the movable body; and a support body configured to support the vibrator actuator, wherein the vibratory actuator includes an actuator main body that contacts the movable body and is configured to vibrate to output a driving force to the movable body, an opposing member that contacts the movable body and is positioned so as to face the actuator main body with the movable body interposed therebetween, and a coupling member that is configured to couple the actuator main body with the opposing member and to bias the actuator main body and the opposing member so as to sandwich the movable body therebetween with the movable body kept displaceable along the shaft, and the support body supports the vibratory actuator so that the vibratory actuator is displaceable along a biasing direction of the coupling member.
