Claims

[Scope of Claim for Utility Model Registration] Consisting of a frame and a door that can be opened and closed within the frame, the utility model is installed on the ceiling or wall of a building, and the door is closed during normal times and opened during emergencies. In the smoke exhaust port for exhausting smoke, a metal elastic plate curved in a direction perpendicular to the longitudinal direction is attached to the four circumferences of the frame opening so as to be in sliding pressure contact with the outer circumference of the door when the door is closed, and , a pair of first support members each supporting a rotation axis of the door are fixedly provided on the back surface of the door, and each of the corresponding first support members is rotatable at a predetermined position at the tip. A pair of second supporting members are attached to the elastic plate of the frame at their respective proximal ends.
A smoke exhaust port characterized in that it is fixedly provided at a proper position at the rear.
