Lens barrel and camera

摘要

A small-sized lens barrel (2) and camera (1) have the following configuration. The lens barrel has a first barrel (30), a second barrel (40) movable between retracted position retracted in the inner diameter side of the first barrel and shooting position shifted toward the incident side in an optical axis direction with respect to the first barrel, a lens (L1) moved relative to the second barrel (40), a support part (80) formed into a ring shape and supported by the end of the first barrel (30) on the exit side in the optical axis direction, the support part (80) being arranged on the inner diameter side of the first barrel (30), a projecting part (45) formed so as to project in the optical axis direction from the end of the second barrel (40) on the exit side in the optical axis direction, and an accommodating part (87) being formed at the support part (80) and accomnnodating the projecting part (45) at the retracted position.
