Patent ID: 8320064

Claim:
A lens barrel comprising: a first frame configured to include a stop portion protruding in an optical-axis direction and hold a first optical element; a first drive unit configured to move the first frame in the optical-axis direction and hold a position in the optical-axis direction of the first frame in a nonenergized state; a second frame configured to include a protrusion protruding in the optical-axis direction and hold a second optical element; a second drive unit configured to move the second frame in the optical-axis direction and not hold a position in the optical-axis direction of the second frame in the nonenergized state; and a shock-absorbing portion provided at least one of the first and second frames, wherein the first frame moves such that it is positioned within a range in the optical-axis direction of the second frame when a state is changed from an energized state to the nonenergized state, and wherein the shock-absorbing portion absorbs a shock that is generated by the second frame against the first frame when the second frame moves in the optical-axis direction in the nonenergized state and hence the protrusion of the second frame contacts the stop portion of the first frame.
