置。[Scope of Claim for Utility Model Registration] (1) A variable power lens and a correction lens are attached to a movable frame that moves while being guided by the fixed barrel in conjunction with the rotation of a cam barrel installed as an outer barrel of the fixed barrel. In a zoom lens barrel having a supported structure, a notched cam is provided which is cut in the direction of the cylinder axis from the end of the cylindrical body, and a flange-shaped cam is formed around the outside of the cylinder so as to bridge this notched cam. a cam barrel having a bayonet claw; a bayonet mounting mechanism consisting of a concave groove along the outer periphery of the fixed barrel and a bayonet locking claw provided on a mounting plate integrated with the base of the fixed barrel; After the bayonet pawl of the cylinder is rotatably fitted into the concave groove of the mounting plate, the rotation restricting means provided on the mounting plate restricts the rotation range of the bayonet pawl and prevents it from escaping. A cam cylinder mounting device characterized by: (2) A plurality of one-side notched cams having a shape cut from one end of the cylindrical body and a plurality of other-side notched cams having a shape cut from the other end of the cylindrical body; A cam cylinder is provided with flanges formed to bridge each notched cam on the outer circumferential portion of each of both ends of the cylindrical body, and the flange on one end side of the cylindrical body serves as a bayonet claw. The cam cylinder mounting device described in (1).
