PROBLEM TO BE SOLVED: To provide a hinge that reduces a size of a gap between an edge part on a pivot side of a swing door and a door stop on a door frame when the swing door is closed, and mitigates unintended movement of a hinge piece when the door is opened.SOLUTION: A hinge includes a fixed-side half body fitted on a door frame side, a movable-side half body fixed on a door side, and a shaft body connecting the fixing-side half body and the movable-side half body. The fixed-side half body includes a fixed-side shaft tube into which an end of the shaft body is inserted, while the movable-side half body includes a movable-side shaft tube into which the other end of the shaft body is inserted. A cam mechanism is formed on a part of an outer peripheral surface of the shaft body in a shaft direction and an inner peripheral surface of the fixed-side shaft tube or the movable-side shaft tube corresponding to the outer peripheral surface, for moving the movable-side shaft tube to a door stop side of the door frame when the door is rotated in a closing direction.SELECTED DRAWING: Figure 3 |
