PROBLEM TO BE SOLVED: To provide a lens barrel that allows at least one of a direction of an optical axis of an optical element with respect to a frame body holding member and a position of the optical element in an optical axis direction to be adjusted after an attachment member is attached.SOLUTION: A lens barrel comprises: a fourth lens holding frame 5d that holds a lens; a stationary barrel 2 that holds the fourth lens holding frame 5d; and a mount member 8 that has a reference section 81 to which a camera main body attached to the stationary barrel 2 is mounted. The mount member 8 comprises: an opening section 82 that is opened so as to penetrate from an object side through an image side. The fourth lens holding frame 5d comprises an adjustment section 56 that adjusts a position of the fourth lens holding frame 5d with respect to the stationary barrel so as to allow at least one of a direction of an optical axis of the lens and a position of the lens in the optical axis direction to be adjusted, and the adjustment section 56 is arranged at a position where the adjustment from the opening section 82 is enabled.SELECTED DRAWING: Figure 2 |
