の改造が許されない場合もあって、この種換気扇を使用
できない欠点があった。Therefore, in the past, the wall around the existing mounting hole was cut out to widen the inner circumference of the mounting hole, which made the installation work extremely troublesome, and in rental housing, etc., it was difficult to remodel the house. There are some cases where this type of ventilation fan cannot be used.

本考案は上記事情に鑑みてなされたものであり、その目
的は、既存の取付孔をそのまま利用して取付け得るとと
もに該取付孔が壁面の隅角部の近傍に形成されている場

要となって取付工事を容易に行い得る換気扇を提供する
にある。The present invention was developed in view of the above circumstances, and its purpose is to enable installation by using existing mounting holes as they are, and also to provide sufficient mounting capacity even when the mounting holes are formed near the corners of a wall. To provide a ventilation fan that can be easily installed without requiring modification work such as cutting out a wall surface.

経路を流通する。By the way, if the mounting hole 33 is formed at the left corner of the wall surface 34 as shown in FIG. 4, and it is impossible to mount it by aligning the center part of the back plate 27 with the center part of the mounting hole 33, In this case, the back plate 27 is fixed to the wall surface 34 so that the case 1 is on the right side with respect to the mounting hole 33, and the intake port 31 and the exhaust port 32 provided on the left side are made to correspond to the mounting hole 33. Connect the pipe 37 and exhaust pipe 38 to the left intake port 3.
1 and the exhaust port 32, and the remaining intake ports 31 and exhaust ports 32 are closed with the lid 40, the intake air flow A' flows into the intake chamber 29 through the intake pipe 37 and the left intake port 31. The exhaust flow B' is taken in from the exhaust chamber 30 to the left exhaust port 3.
2 and the exhaust pipe, but flow through the same route as shown in FIG. 3.
