11と外装材3の隙間に設けられる。The hood 13 is, as shown in FIG.
It opens downward and the side surface 13a is curved. The upper surface 13b is inclined downward from the exterior material 3 for drainage, and a drain port 14 is formed between the upper surface 13b and the side surface 13a. Further, as shown in FIG. 3, insertion portions 25 bent in an L shape are formed on both sides of the hood 13 and are inserted into the insertion portions 22 of the mounting frame 11. In the inserted state, the portion of the insertion portion 25 that comes into contact with the exterior material 3 is pressed by the elasticity of the insertion portion 22. Also, the upper surface 13b of the hood 13
Is positioned by hitting the upper end of the mounting frame 11. Reference numeral 16 denotes a special rivet, which has a structure as shown in FIG. 6, and the shaft 16a is pulled out from the cylinder 16b so that both sides in the side surface 13a of the hood 13 are fixed together with the mounting frame 11. Accordingly, when the side surface 13a is curved, the fixing position can be fixed even in a narrow space where it is difficult to operate with a tool such as a screwdriver. Reference numeral 26 denotes a caulking material, which is provided in a gap between the hood 13 and the exterior material 3 and a gap between the mounting frame 11 and the exterior material 3.

Then, a plurality of base bars 8 made of piece material are previously interposed between the interior material 2 and the exterior material 3 around the holes 4 and 5, and the pipe portion 6a of the base pipe 6 is inserted from the hole 4 of the interior material 2. Then, the outer flange portion 6b is brought into contact with the outer surface of the interior material 3 and is fixed to the base rail 8 by a fixing tool 15. In this state, the attachment portion 7b of the ventilation fan 7 is fitted and attached to the pipe portion 6a of the base pipe 6.

なり換気可能となる。Next, the operation will be described. When the ventilation fan 7 is stopped, as shown by the solid line in FIG. 1, the shutter 12 has the hanging hole 5 closed due to its own weight. Therefore, the back wind from the outdoor side does not blow into the room from the hood 13 through the hole 5. When the ventilation fan 7 is operating, the shutter 12 is rotated by the wind pressure of the ventilation fan 7 as shown by the two-dot chain line.
Rotate with 3 as the axis. As a result, the hole 5 is opened and ventilation is possible.
