Abstract
A lens barrel includes: a first lens holding frame; a fixed barrel holding the first lens holding frame and including an elongated window provided radially; and a first step-type eccentric roller rotatably fixed to the first lens holding frame. The first step-type eccentric roller includes usable and non-usable regions on a periphery substantially perpendicular to the rotation axis, a distance from a center of the rotation axis to any point within any one of the usable regions is constant, and the distance is different for each of the usable regions, and the first step-type eccentric roller is fixed to the first lens holding frame by rotating the first step-type eccentric roller about the rotation axis, changing an engagement position between one of the usable regions and a side forming the polygonal shape of the elongated window, and moving the lens group parallel to an optical axis to perform shift adjustment.
