Abstract:
A drive unit includes a lens frame configured to support a lens, a movable body located outside the lens and configured to be movable with the lens frame, and a vibratory actuator configured to drive the movable body. The vibratory actuator includes an actuator main body contacting the movable body, an opposite member provided at a position which is opposite to the actuator main body so that the movable body is sandwiched between the actuator main body and the opposite member, and a connecting member configured to connect the actuator main body and the opposite member and to bias them toward the movable body. The connecting member is not provided at a side of the movable body where the lens frame is provided, but is provided at an opposite side of the movable body to the side where the lens frame is provided, as viewed in the optical direction.
