Claims

[Claim for Utility Model Registration] A rotary lever rotatably supported by the chassis is brought into contact with an abutting portion provided on the chassis side and provided at the working end of the rotary lever. a regulating means for preventing movement of the working end; and a restricting means for preventing the working end from moving in one direction; The rotational force is applied to the rotational lever by pressing a resilient means for energizing the power and a pressed portion located on the reaction end side of the rotational lever at a position where the resilient means is connected. a pressing means for rotating the chassis and the rotary lever; a guide hole extending in a substantially arc shape is formed in one of the chassis and the rotary lever, and an engagement pin slidably engages with the guide hole in the other; is provided, and when the rotating lever is not pressed by the pressing means, the pivoting fulcrum of the rotating lever is in a position where it comes into contact with one end edge of the guide hole of the engaging pin, and the elasticity of the resilient means is The generated force acts as a crimping force that presses the contact portion of the rotary lever against one end of the regulating means, and when the rotary lever is pressed by the pressing means, the pivot point of the rotary lever is The pressed part is in a position where it comes into contact with the pressing means, and the resilient force of the resilient means acts as a pressing force that presses the contacting part of the rotary lever against the other end of the regulating means. Rotating lever rotation mechanism.
