Abstract
Wind noise is suppressed while an air-blowing performance is maintained.An indoor unit 1 of an air conditioner includes a cross flow fan 10 and a rear guider 20 and a stabilizer 32 which are provided on the respective sides of the outer periphery of the cross flow fan 10 to form an air passage. Each of the rear guider 20 and the stabilizer 32 has, at least at a part in the axial direction which part is on the leading end side, twisted portions 23, 37. In the circumferential direction of the cross flow fan 10, each twisted portion 23, 37 is deviated from the axial direction of the cross flow fan 10 gradually from one end to the other end.
