PROBLEM TO BE SOLVED: To solve the following problems: in conventional means for opening/closing a door, many of them use a hydraulic piston cylinder or restoring force of a coil spring but are complicated in structure; as the conventional reinforcement of a door is insufficient, a side opposite to a side where a hinge is mounted hangs down and is supported by a caster, which requires sweeping of an area where the door opens so as to allow the passing of the caster; and there is a method of hanging the opposite side by an auxiliary wire, but the method is troublesome. SOLUTION: In a door and a hinge, and a method of mounting the hinge, a shaft (1) is covered with a cylinder (2), a push bolt (2a) is formed in the upper part of the cylinder (2), the push bolt (2a) exists in the shaft (1) through spheres (2b) to eliminate friction, the door (4) is automatically closed by inclining a position where the hinge is mounted, and a reinforcement (4b) is installed obliquely at 45°to obtain a solid door and hinge.
