Abstract
A lens barrel includes an oscillatory wave motor which drives a lens; a manual connection ring which is operated manually to cause the lens to move along an optical axis; a slip ring which is in contact with the manual connection ring; a roller which is in contact with the slip ring and with the oscillatory wave motor; and a roller support ring which supports the roller. The slip ring is structured such that frictional resistance on a contact surface between the manual connection ring and the slip ring is smaller than frictional resistance on a contact surface between the roller and the slip ring.
