ムーズに回転する。According to the seventh aspect of the present invention, one end, which is the closed end of the concave groove, is formed into a shape matching the outer peripheral shape of the upper hinge pin so as to make circumferential contact with the upper hinge pin, and the stopper is an elastic plate. The center of the strip-shaped body is bent transversely to form a V-shape, and the protruding side of the V-shaped elastic plate-like body is directed downward, and the one end of the V-shaped elastic plate-like body is bent downward to form a bent portion. Since the other end side of the V-shaped elastic plate-like member is fixed to the concave groove so that the curved portion abuts on the upper hinge pin at the other end side which is the opening end of the concave groove, the upper hinge pin is Surface contact is made on the closed end side of the concave groove, and line contact is made with the bent portion of the V-shaped elastic plate member. Therefore, since the upper hinge pin is in a state in which a part of the upper hinge pin is in line contact with the V-shaped elastic plate-like member, the upper hinge pin rotates smoothly with less frictional resistance.

でき得る。However, it is necessary to provide an escape hole for the bent portion when the V-shaped elastic plate member is pushed down. Further, in order to activate the stopper function and prevent the rotary door from being removed, the force of pushing one end of the V-shaped elastic plate-like member downward may be released. By doing so, the one end returns from the flat plate shape to the original V-shape due to the elasticity of the plate-like body, so the concave groove is closed again by the V-shaped elastic plate-like body which is the stopper, and the upper hinge pin moves. become unable. Therefore, the opening and closing of the groove can be easily performed only by operating the stopper.
