PROBLEM TO BE SOLVED: To provide a lens barrel that enables an eccentricity adjustment between a lens holding frame holding a lens and a frame member holding the lens holding frame to be surely and highly accurately made by a simple configuration. ! SOLUTION: A lens barrel 1 capable of making an eccentricity adjustment of a lens comprises: a lens 13 of which a centering adjustment is made; a first holding frame 23 that has an outer peripheral surface and holds the lens; a second holding frame 25 that has a counter surface facing the outer peripheral surface and holds the first holding frame capable of being displaced in a direction orthogonal to an optical axis O; an adjustment member 56 that, when displacing the first holding frame in a direction orthogonal to the optical axis with respect to the second holding frame, is arranged detachably between the outer peripheral surface for maintaining the first holding frame at the displacement location and the counter surface; a first pressure member 52 that pre |
