For example, in the above-described embodiment, the above-described hardware 1 is used as the hardware for the underfloor ventilation port. However, the shape of the ventilation slit is not particularly limited as long as it has a predetermined effective ventilation area. Absent. In addition, a wire mesh such as that used for conventional underfloor vent fittings on the main plate,
It is also possible to use a device provided with a slide type opening / closing plate for opening and closing the ventilation slit.

In the above embodiment, the metal fittings for the underfloor ventilation openings are formed by bending a stainless steel plate material, but may be formed by bending a plated steel plate.

The underfloor ventilation fitting in the present invention is:
The main plate portion and the fixing plate portion can be separately manufactured as the same material or different materials, and can be manufactured by joining them. When the main plate portion and the fixed plate portion are made of the same material, they can be made of a material such as stainless steel, plated steel plate, or cast iron. In the case of manufacturing with a different material, the main plate portion is manufactured with a material such as stainless steel, plated steel plate, cast iron, and a material different from the material of the main plate portion is selected with a material such as stainless steel, plated steel plate, plastic, and the like. A fixing plate portion is prepared, and these are joined to form a metal fitting for an underfloor ventilation port. Examples of a method of joining the main plate portion and the fixed plate portion include welding, screwing, and adhesion.

Further, in the above embodiment,
Although the nail 9 is used, it goes without saying that a screw or the like can be used.
