Zusammenfassung:To provide a fan shroud which can inhibit airflow from the vehicle rear side of the fan shroud from entering the inside of the fan shroud and inhibits deterioration of ventilation performance of airflow passing through the inside of the fan shroud to the vehicle rear side.SOLUTION: In a fan shroud 10, vent holes 46A to 46D are covered by guide walls 48A to 48D from the vehicle rear side. Airflow flowing from the vehicle rear side to the vehicle front side of a bottom wall 26 is blocked by the guide walls 48A to 48D to be inhibited from entering the vent holes 46A to 46D. Further, airflow that has passed from the vehicle front side through the vent holes 46A to 46D flows to the rotation direction side of a fan 36. Such airflow is attracted to swirling airflow that has passed through a second cylinder part 28 by rotation of the fan 36, and passing of the airflow through the vent holes 46A to 46D is facilitated.SELECTED DRAWING: Figure 1 【課題】ファンシュラウドの内側を車両後側へ通る気流の通風性の低下を抑制でき、ファンシュラウドの車両後側からの気流がファンシュラウドの内側へ入ることを抑制できるファンシュラウドを得る。【解決手段】本ファンシュラウド10では、通風孔46A〜46Dは、誘導壁48A〜48Dによって車両後側から覆われる。底壁26の車両後側から車両前側へ流れる気流は、誘導壁48A〜48Dによって遮られ、通風孔46A〜46Dへ入ることが抑制される。また、車両前側から通風孔46A〜46Dを通った気流は、ファン36の回転方向側へ流れ出る。このような気流は、ファン36の回転によって第2筒状部28を通った旋回気流に引き寄せられ、このような気流の通風孔46A〜46Dの通過が促進される。【選択図】図1
