理等も容易に行なうことができるものである。As described above, according to this embodiment, the tapered part 30 at the tip of the connecting cylinder 27 is connected and fixed to the exhaust duct 35, and then the casing 7 is disposed in the mounting opening 5 of the ceiling plate 1. The exhaust port body 23 is fitted into the exhaust port 9 from inside the casing 7, and the threaded portion 25 of the exhaust port body 23 is threadedly connected to the threaded portion 29 at the proximal end of the connecting cylinder body 27. Therefore, the exhaust port 9 of the casing 7, that is, the exhaust port body 23, can be connected and attached to the exhaust duct 35 from the indoor 3 side, and therefore, the attachment can be performed even after the ceiling plate 1 is attached to the roof edge 2. Unlike conventional methods, there are no restrictions on installation time, making it extremely convenient.
Further, the blower 12 can be easily attached to and detached from the casing 7 using the thumbscrews 20, and
The casing 7 can be easily attached to and removed from the exhaust duct 35 by simply screwing the exhaust port body 23 into and out of the base end of the connecting cylinder 27, and therefore maintenance, inspection, repair, etc. can be easily performed. It is something that can be done.

ケーシング７の右側板に複数本のねじによって取付ける
場合に比し取付けが簡単である。Moreover, according to this embodiment, the flexible portion 28 is provided on the connecting cylinder 27.
Furthermore, since the diameter of the air intake port 9 is made larger than the outer diameter of the exhaust port body 23, even if there is an axial position misalignment between the exhaust port 9 and the exhaust duct 35, this can be removed from the exhaust port. It can be sufficiently absorbed by the body 23 and the flexible part 28, and in particular, the flange part 24 of the exhaust port body 23 is connected to the threaded part 25° 29.
Since the flange 24 is pressed into contact with the right side plate of the casing 7 through the seal member 26 by screwing, the attachment is easier than, for example, when the flange 24 is attached to the right side plate of the casing 7 with a plurality of screws.
