。[Scope of Claim for Utility Model Registration] 1. An automatic aperture adjustment device that automatically changes the diameter of the aperture according to the intensity of light from the subject, which has a friction piece at one end that comes into contact with an aperture drive ring that moves the aperture blades; a slider having a pusher therein that is biased by a first elastic member so that a portion of the slider protrudes from the other end; and the slider is slid perpendicularly to the rotating surface of the aperture drive ring. a second elastic member that biases the slider in a direction away from the aperture drive ring with a biasing force weaker than that of the first elastic member; An aperture locking device for an auto iris, comprising an operating member that presses the mover against the biasing force of the second elastic member. 2. In the aperture locking device according to claim 1, the holding means is the cylinder 21, and the first
An aperture locking device characterized in that the elastic member 25 and the second elastic member 22 are constituted by compression springs provided in the slider 20 and the cylinder 21, respectively.
