Abstract
A blade open-close device includes an aperture blade having an opening on an optical axis of a lens and extending in an intersecting direction intersecting with an optical axis direction of the optical axis of the lens, a blade movable in the intersecting direction, a drive moving the blade to a closing position to cover the opening or an opening position to uncover the opening, a transmission member transmitting a driving force of the drive to the blade, a body to which the aperture blade, the blade, the drive, and the transmission member are attached, and a restrictor restricting movement of the blade in the intersecting direction. The aperture blade and the transmission member are located between the body and the blade in the optical axis direction. The body has an upper surface facing the aperture blade and the transmission member. The restrictor is located on the upper surface.
