PROBLEM TO BE SOLVED: To provide fittings enlarging the scope of selection of manufacturing processes and a manufacturing device while ensuring fire protecting performance of a door body. SOLUTION: The fittings can ensure the fire protecting performance for shutting off indoor and outdoor spaces and preventing a fire from spreading when a fire occurs, by preventing a panel unit 12 from dropping even if a thermal insulating material 9 is melted by the fire as the panel unit 12 is supported by a supporting body 13. Furthermore, since a plurality of panel units 12 are positioned in a frame member 7 by the supporting body 13, the scope of selection of manufacturing procedures and a manufacturing device of the door 6 can be enlarged through, for example, installation of the heat insulating material 9 like a solid plate and pouring the thermal insulating material 9 before it is hardened. By selecting the manufacturing procedures and manufacturing device in accordance with various conditions or the like, a period of time required for manufacture can be shortened and manufacturing cost can be reduced.
