Abstract
A lens barrel includes a lens and a holding member holds the lens. A guide barrel guides the holding member linearly movably in an optical axis direction of the lens. A cam ring is rotatably held about an optical axis of the lens with respect to the guide barrel and surrounds the guide barrel. The cam ring has a first contact portion opposed to the fixed member fixed to the guide barrel, in the optical axis direction. The fixed member has a second contact portion opposed to the first contact portion in the optical axis direction. When the cam ring is moved by an external force to approach the fixed member in the optical axis direction, the first contact portion and the second contact portion are brought into contact with each other, whereby rotation of the cam ring about the optical axis is restricted.
