PROBLEM TO BE SOLVED: To provide a door and fittings excellent in fireproofness while having synthetic resin made handles.SOLUTION: An openable/closable door for partitioning two spaces has: a lock mechanism which is locked for maintaining a closed state of the door; synthetic resin made handles which are arranged at sides of the spaces, respectively, and operate the lock mechanism to a locked state or a lock-released state so as to be switchable; and openings which a connecting member for connecting the handles and a transmission member for transmitting operations of the handles to the lock mechanism penetrate, and are covered with the handles. The door also comprises: metal-made surface materials facing the spaces, respectively; an opening covering member having hole parts which the connecting member and the transmission member penetrate, and are smaller than the openings, and attached to the opening of at least one surface material while covering it; and a thermal expansion member which is arranged at the opening covering member, expanded when heated, and covers the hole parts. |
