However, particularly in the latter prior art double trap type pipe holding structure,
Since the worker winds the putty 5 by hand, the gap t2 between the outer end of the putty 5 and the partition plate 6 between the fan chamber and the machine chamber and the gap t1 are likely to vary. There is a problem that the putty 5 comes into contact with the partition plate 6 due to the vibrations, and abnormal noise is generated, and the pipes 3 are too close to each other.

Accordingly, an object of the present invention is to provide an air conditioner that can maintain a constant gap between the above-mentioned double trap type pipes, reduce vibration and abnormal noise of the pipes, and can easily perform the work of attaching the pipes to the pipes. An object of the present invention is to provide a pipe holding structure.

[0006]

In order to achieve the above object, a pipe holding structure according to the present invention has a structure as shown in FIG.
