成してあるレンズ鏡胴。 A lens holding member that holds a lens is fitted into the outer fitting member in a state where relative movement is free in the optical axis direction of the lens while slidingly contacting each other, and the lens holding member is in contact with the inner circumferential surface of the lens holding member and attached to the outside. In a lens barrel that is provided with a pressing member that holds the lens on a lens holding member by force, at least relative movement of these members in the optical axis direction of the sliding contact portion between the lens holding member and the external fitting member. Accordingly, a lens mirror is formed with a loose fitting portion in which the outer circumferential surface of the lens holding member and the inner circumferential surface of the outer fitting member are separated from each other in a portion corresponding to a location where at least both ends of the holding member are located. Torso.
