[Scope of Claim for Utility Model Registration] 1. An aperture setting member that is placed at a position according to the set value by an aperture setting operation, and a position corresponding to the set value by the aperture setting member by movement of the aperture member on the side of the camera body. an aperture blade drive member that moves to narrow down the aperture blades to the aperture value set by the aperture setting member; and an aperture blade drive member that moves when the movement of the aperture blade drive member is restricted by the aperture setting member and hits a stationary part; and a bounce prevention member that prevents the lens from moving backwards due to reaction. 2. The lens aperture device according to claim 1, wherein the bounce prevention member is rotatably attached to the aperture blade drive member. 3. The lens narrowing device according to claim 1, wherein the bounce prevention member integrally includes a weight as an inertial body. 4. The lens aperture device according to claim 1, wherein the bounce prevention member is moved by an inertial member provided in parallel with the aperture blade drive member.
