Zusammenfassung:	A lens barrel (1,2,3) comprising: a fixed tube section (10,20,30) that is mounted to a camera body (B); a movable tube section (11,21,31) that is movably screwed to the fixed tube section (10,20,30); and a nut member (12,22,32) that, screwed to the movable tube section (20), is abutting on the top end (10b) of the fixed tube section (10,20,30). The nut member (12) acts as a double nut, preventing rotation of the fixed tube section (10, 20, 30) and the movable tube section (11, 21, 31) relative to each other.
