ることを特徴とするカメラ用絞り機構。(1) An aperture drive member that reciprocates over a certain range in relation to the release operation of the camera's release button. A diaphragm regulating member that moves together with the diaphragm operation frame according to the drive member, a locked member configured to interlock with the diaphragm regulating member, a locking member biased in the direction of the locked member, and the locking member. holding means for holding the member in a direction opposite to the biasing direction; holding means for holding and displacing the locking member in a direction opposite to the biasing direction; The locking member has a release member that is in pressure contact with the locking member, and when the aperture regulating member moves forward, the locking member can lock the locked member immediately by releasing the hold by the holding means, and When the release member is moved, the locking member is attached by displacing the release member.
A diaphragm mechanism for a camera, characterized in that the aperture mechanism for a camera is displaced in a direction opposite to the force direction, thereby releasing the locking of the locked member by the locking member during the forward movement.

するカメラ用絞り機構。(2) In claim (1), the aperture regulating member has a pin, and the locked member or the connecting member connected to the locked member is rotatably supported and supports the pin. It is characterized by having two intervening parts, and formed so that the distance between the part of the two prongs that abuts the pin and the center of rotation is always constant within the movable range of the aperture ruler 30 member.
