2. Description of the Related Art In a conventional rotation angle restriction hinge disclosed in Japanese Utility Model Laid-Open No. 82078/1985, a washer plate is fitted to a pivot shaft that rotatably connects a fixed blade plate and a movable blade plate. By providing a fan-shaped protrusion on one side, when the door is closed, one end face of the fan-shaped protrusion is brought into contact with the belly face of the fixed blade, and when the door is opened, the other end face of the fan-shaped protrusion is brought into contact with the belly face of the movable blade. , The opening and closing angle of the door is regulated according to the central angle of the fan-shaped protrusion.

However, the washer plate fitted to the pivot of the hinge from which the door is suspended is rotated by the fan-shaped projections contacting the fixed blades and the movable blades at each end of opening and closing of the door. Since a large external force derived from the moment is applied, a washer plate made of a relatively thin plate is likely to be distorted or deformed, which causes a problem in durability.
