摘要： The air conditioner of the present invention is equipped, within a casing 2, with a cylindrical bell mouth 8 for introducing room air, a centrifugal fan 10 for radially blowing off air sucked in through the bell mouth 8, and a heat exchanger 9 provided opposite to an air outlet 10b of the centrifugal fan 10. A shroud 5 of the centrifugal fan 10 has an annular guide portion 5c which is provided radially outside the blade support portion 5b and which abuts on an annular blade support portion 5b and extends toward the suction side in the axial direction. By virtue of this guide portion 5c, air blow noise can be reduced effectively.
