機構。[Claims for Utility Model Registration] A cup-type mounting member and a frame-type mounting member that are fixed to the door and the side plate, respectively, are rotatably connected by a plurality of link plates, and an outer The link plate is provided with a cam whose tip protrudes in a direction perpendicular to the link plate, and one end of a torsion coil spring is brought into contact with the cam, and the other end is locked to a frame-type mounting member. In the catch mechanism, a neutral constituting surface is formed on the cam surface of the cam to be wide in the direction of rotation, and a catch constituting surface is recessed at the end of the neutral constituting surface, and as the cam surface moves, the torsion coil spring is wound. A hinge catch mechanism characterized in that a portion is movable and is in an unfixed state.
