Zusammenfassung:	[Solution] The lens barrel (1) in this invention has the following: a fixed tube section (10) that is mounted to a camera body (B); a movable tube section (20) that is movably screwed to the fixed tube section (10); and a nut member (12) that, screwed to the movable tube section (20), is energized towards top end (10b) of the fixed tube section (10). The nut member (12) acts as a double nut, making it possible to inhibit rotation of the fixed tube section (10) and the movable tube section (20) relative to each other, preventing focus or zoom slippage or the like.
