Further, since the pipe body is provided with an outer gradient which becomes lower as it goes toward the outdoor side,
It can be easily installed in a state having an outer slope, and the ventilation fan main body can be easily fixed and held parallel to the wall surface.

Further, since a flange having a diameter larger than the inner diameter of the opening provided in the chamber wall is provided at one end, and a spring having a shape capable of sandwiching the wall material is provided on the flange wall surface side, the two chambers sandwiching the wall are provided. Installation work can be completed from one room, and workability can be improved without having to go back and forth between both rooms.

Further, the pipe end face has a flange having a diameter larger than the inner diameter of the opening provided in the indoor partition wall, the ventilation fan main body is installed on one flange side, and the decorative grill of the ventilation fan main body is installed on the other flange side alone. Since it can be installed in the room, a makeup grill can be installed in the exposed parts of both rooms without impairing the aesthetics of the room.
