PROBLEM TO BE SOLVED: To provide an outdoor unit of an air conditioner capable of restricting reduction of an effective flow passage area at the discharging side of a propeller fan and attaining a high amount of air and a high efficiency.MEANS FOR SOLVING THE PROBLEM: An outdoor unit of an air conditioner comprises an outdoor heat exchanger 105 and a propeller fan 101 for use in aerating air to this outdoor heat exchanger. In addition, an inner circumferential surface of a ring 111 at a downstream side of the propeller fan is provided with a plurality of stator blades 110 in its circumferential direction. An inner circumferential side of the plurality of stator blades installed in its circumferential direction is formed with a through space 10. With this arrangement, it is possible to restrict an inverse flow region generated at a discharging side of the propeller fan and to set a high amount of air and a high efficiency.SELECTED DRAWING: Figure 1 【課題】プロペラファン吐出側の有効流路面積の減少を抑制して、高風量化や高効率化を図ることのできる空気調和機の室外ユニットを得る。【課題手段】空気調和機の室外ユニットは、室外熱交換器１０５と、この室外熱交換器に通風するためのプロペラファン１０１を備える。また、前記プロペラファンの下流側におけるリング１１１の内周面には、周方向に複数枚の静翼１１０が放射状に設置されている。この周方向に複数枚設置された前記静翼の内周側には貫通空間１０が形成されている。これにより、プロペラファンの吐出側に発生する逆流領域を抑制して、高風量化と高効率化を図ることができる。【選択図】図１
