PURPOSE:To simplify an operation for installing a lens to a lens frame, and also to elastically absorb and correct deformation of the lens caused by a variation of a diameter of the lens, its thickness, and others, by providing a stopper for controlling the lens provided with an elastic part having a tapered surface, in the optical axis direction, and a receiving part of the elastic part of the lens. CONSTITUTION:On an outside circumferential edge 10a of a lens 10, an elastic part 11 is formed projectingly as one body at 4 places. The elastic part 11 is formed by providing extendingly a lateral V-bending part 13 from a project- molded base end 12 from the outside circumferential edge 10a of the lens 10, and providing a tapered surface 14 which is made to press-contact with a tapered surface 22 provided on a receiving part 21 of a lens frame 20, on its one side part 13a. The lens frame 20 has the receiving part 21 as one body on an inside circumferential edge 20a, and on this receiving part 21, the tapered surface 22 provided with a press-contact surface corresponding to the tapered surface 14 of the elastic part 11, and a stopper 23 for controlling the lens 10 in the optical axis direction are projectingly provided. |
