PROBLEM TO BE SOLVED: To provide a lens barrel that is excellent in assemblability without increasing the number of components, and can suppress a damage of a pin part of a potentiometer due to external force to be applied when assembled.SOLUTION: A lens barrel comprises a movable part (151), and the movable part includes: a first barrel (23) that fixes position detection means (15) performing a position detection by movement of the movable part in a prescribed direction; a second barrel (14 and 16) that engages with the movable part, and has a groove part (161) for moving the movable part in the prescribed direction; and an assembly mechanism for assembling the second barrel into the first barrel. The assembly mechanism has: a first concavity part (231a1) provided in one of the first barrel and the second barrel and for guiding the movable part to an introduction part (161a) of the groove part; and a convexity part (141) that is provided in other of the first barrel and the second barrel, and engages with the first concavity part. |
