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.

Abstract: A lens barrel includes: a first ring; a second ring that switches between a first position and a second position by sliding in an optical axis direction; a plurality of biasing mechanisms that are provided on one of the first ring and the second ring, and providing adjustable biasing force in a radial direction; and a locking portion provided on the other of the first ring and the second ring on which the plurality of biasing mechanisms are not provided. The plurality of biasing mechanisms each include an elastic component having a contact portion and a biasing component that biases the elastic component. The first ring and the second ring are integrally rotatable when the contact portion contacts the locking portion which opposes the contact portion when the second ring is at the second position.

Abstract: An electrical storage device includes an electrical storage element and an electrolytic solution. The electrical storage element is formed of an anode body, a cathode body facing the anode body, and a separator interposed between the anode body and the cathode body. The separator includes a separator substrate and a conductive polymer adhering to the separator substrate. The electrical storage element is impregnated with the electrolytic solution. The separator includes a first surface layer having a first surface facing the anode body and a second surface layer having a second surface facing the cathode body. The first surface layer includes a first region that is not provided with the conductive polymer, and the second surface layer includes a second region provided with the conductive polymer.
