A lens barrel which allows efficient interlock between a cylindrical member such as a moving cam ring and a component such as a viewfinder cam plate or a strobe cam plate, without size-increasing. The lens barrel comprises a first cylindrical member, and a second cylindrical member that is disposed so as to receive the first cylindrical member, and includes a guiding part at an inner circumferential surface thereof. The guiding part includes a groove-form hole part that penetrates the second cylindrical member, and the first cylindrical member includes a follower part that follows the guiding part having the groove-form hole part. |
