Abstract

In an air conditioner, at an outdoor side end of a ventilation duct (75), an auxiliary duct (78) having an outlet side end (80) of an approximately semicircular shape twisted by about 90° with respect to a coupling portion (79) for the ventilation duct (75) is coupled. When the coupling portion (79) of the auxiliary duct (78) is adapted to have cross sections of different diameters, it can be coupled to a ventilation duct (75) having a small diameter. Further, if the outlet side end opening (83) is cut obliquely, air circulation is not hindered even when it is in contact with a wall surface of the weather cover (81).
