Claim:
A lens barrel including a first lens group for taking in light rays incident thereon from an object side along a first optical axis, a barrel section coaxial with the first optical axis and supporting the first lens group, and a reflective section for bending the light rays emitted from the first lens group to thereby guide the light rays along a second optical axis intersecting the first optical axis, the barrel section extending toward the object side along the first optical axis or retracting toward an opposite side from the object side whereby the first lens group is moved along the first optical axis, wherein the barrel section comprises: a fixed barrel formed with a first cam portion inclined with respect to a circumferential direction, and a second cam portion continuous with an object-side end of the first cam portion, and a movable barrel provided with a cam engaging part for slidable engagement with the first cam portion and the second cam portion, and wherein the reflective section is configured to be moved along the second optical axis between a standby position and a shooting position when the cam engaging part of the movable barrel is in engagement with the second cam portion of the fixed barrel.
