In this case, according to the present embodiment, the elastic force of the seal member 34, which is elastically deformable in the direction opposite to the guide rails 26, is interposed between the guide rails 26 and the apparatus main body 11 so that the elastic force is increased. As a result, the guide rail 26 is pressed against the heat exchanger 25, and as a result, no gap is generated between the heat exchanger 25 and the support member 26. Therefore, the exhaust air A and the intake air are not generated. It does not mix with B.

Further, according to this embodiment, as described above, since the guide rail 26 can be displaced in the above-mentioned direction via the seal member 34, when the heat exchanger 25 is inserted and arranged in the guide rail 26.
