<p>PROBLEM TO BE SOLVED: To provide a hanging device of a door capable of preventing fingers from being put between the side wall of the door and a door frame in an opening and closing pivot side of the door for hanging the door in an openable manner and, at the same time, reducing degrees of sliding contact between the side wall of the door and an air-tightness holding and fire resisting packing mounted to the door frame side to reduce extents of damage in abrasion, etc., of the packing. SOLUTION: A loading position of an opening and closing pivot O of a door for loading the side wall 3 on a pivot hinge side of the door to the semi-arc door is the position slightly separated from the center 01 of the semi-arc side wall 3 within a range between a radius r1 from the center 01 of the semi-arc side door 3 to the middle point of the side wall 3 and a radius r2 at a right angle to the radius r1 and to the front side panel 1 toward the side wall 3 and the opening direction of the door or the interception with the rear side panel 2. By the constitution, not only a finger holding, but also the abrasion of an air-tightness holding and fire resisting packing P can be prevented.</p> |
