Abstract

PURPOSE:To ensure the simple and stable holding of a lens without imparing the lens performance, by putting a lens holding member having the elasticity into a lens barrel along with the lens. CONSTITUTION:A stage part 11a is provided to a lens frame 11 to form a small thickness part 11b, and a detaining groove part 11c is formed on the inner surface of the part 11b to detain a holder ring 12 made of resin with elasticity. A detaining part 12c is formed along the fringe of the circular main body 12a of the ring 12 via a split groove 12b. With the ring 12, the holding part 13a formed at the circumference of a lens 13 abutes to the stage part 11a which is smaller than the inner diameter of the part 11b. The part of the body 12a is pressed to the lens 13. Thus the outer diameter of the body 12a is increased, and the part 12c is detained to the part 11c. The lens 13 is fixed within the frame 11.
