Title: LENS BARREL
Abstract:
 Provided is a lens barrel that can be reduced in size. A lens barrel (20) is provided with a holding frame (400) and a retractable lens frame (401). The retractable lens frame (401) holds a lens (L3), and moves around a retractable shaft (501), which is parallel to the optical axis, with respect to the holding frame (400) in the transition period between a shootable state and a stored state. The retractable lens frame (401) has at least three contact portions (603). The at least three contact portions (603) are in contact with the holding frame (400) at locations different from the retractable shaft (501). The contact between the contact portions (603) and the holding frame (400) restricts the movement of the retractable lens frame (401) in the optical axis direction. At least one of the contact portions (603) is provided on the retractable lens frame (401) so as to overlap with the lens (L3) in a direction perpendicular to the optical axis.
