Abstract
It is an object of the present disclosure to provide a lens barrel with which looseness caused by a gap formed between a fixed barrel and a cam barrel can be effectively suppressed without increasing the rotational torque of the cam barrel, as well as a camera equipped with this lens barrel. A lens barrelcomprises first to seventh lens group unitsto, a substantially cylindrical rectilinear barrel, a substantially cylindrical cam barrel, and spacersand. The cam barrelmoves the third to seventh lens group unitstoin the optical axis OP direction by being rotated with respect to the rectilinear barrelin a state in which main cam followersand main cam groovesare engaged with each other. The spacersandprotrude in the radial direction from the rectilinear barreland come into contact with the cam barrelso as to suppress looseness between the rectilinear barreland the cam barrel, and the length in the optical axis OP direction is equal to or greater than the amount of movement of the cam barrelin the optical axis OP direction with respect to the rectilinear barrel
