Zusammenfassung:To provide an axial flow fan which can efficiently discharge a fluid.SOLUTION: An axial flow fan includes: an impeller which rotates around a rotary axis extending in a vertical direction; a motor which rotationally drives the impeller; and a housing 403 disposed at the radial outer side relative to the impeller and the motor. The housing has a hole 4201A penetrating through the housing in a radial direction. An inner wall surface of the housing has: a first wall part forming a narrow gap with a radial outer edge part of the impeller; and a second wall part forming a wide gap with the radial outer edge part. The hole is provided at the first wall part.SELECTED DRAWING: Figure 10 【課題】水分を効率良く排出することができる軸流ファンを提供する。【解決手段】軸流ファンは、上下方向に延びる回転軸を中心に回転するインペラと、前記インペラを回転駆動させるモータと、前記インペラおよび前記モータよりも径方向外側に配置されるハウジング４０３と、を備え、前記ハウジングは、径方向に貫通する孔４２０１Ａを有し、前記ハウジングの内壁面は、前記インペラの径方向外縁部との間隙が狭い第１壁部と、前記径方向外縁部との間隙が広い第２壁部と、を有し、前記孔は、前記第１壁部に設けられる。【選択図】図１０
