は、折曲片３ａが内向きに形成されている。(Example) Next, an example of the present invention will be described in detail with reference to the drawings. 1 is a ventilation surface door body formed from a metal plate, in which a ventilation hole 2 is formed as in the conventional case,
The upper part 2a is made to bulge outward, and the lower part 2a is made to bulge outward.
b is bulged inward. Reference numeral 3 denotes a fireproof cover plate made of a metal plate, which is attached to the outside of the ventilation surface door main body 1 via a mounting bracket 4 so as to cover the ventilation hole 2. Further, a bent piece 3a is formed at the lower end of the fire protection cover plate 3 so as to face inward.
（作用）
本考案に係る換気面戸は、上記のように構成さ
