Inside a blown-out air duct in the air conditioner through which conditioned air reaches a blowing-out port there is provided a rectifying box having a air passage therein, for rectifying a flow of the conditioned air toward a predetermined flowing direction in order to prevent any dew condensation at the blowing-out port in the air conditioner. In the meantime, in order to suppress noise, rectifying plates (44) for reducing an inflowing angle of air flowing into the fin tips of a heat exchanger (37) are interposed between an axial fan (40) and the heat exchanger (37) for taking in the air from the axial fan (40) for heat exchanging. <IMAGE> <IMAGE>
