To prevent water from entering a motor cooling air inlet even if air within a scroll flows so as to wind up upwardly.SOLUTION: A motor cooling air inlet is formed in the side wall portion of a scroll at the downstream side of an air flowing direction and at a portion upwardly apart from a bottom wall portion. Guide portions 21a and 21b which guide water sticking to an upper wall portion 15a in the outlet direction of the scroll and in the direction apart from the motor cooling air inlet are provided on the upper wall portion 15a at the downstream side of the air flowing direction relative to a blower fan in the scroll.SELECTED DRAWING: Figure 5

    【課題】スクロール内の空気が上方へ巻き上がるように流れた場合であっても、モータ冷却風取入口に水が浸入するのを抑制する。【解決手段】スクロールの空気流れ方向下流側の側壁部には、底壁部から上方に離れた部位にモータ冷却風取入口が形成されている。スクロールにおける送風用ファンよりも空気流れ方向下流側の上壁部15aには、上壁部15aに付着した水をスクロールの出口方向かつモータ冷却風取入口から離れる方向に案内する案内部21a、21bが設けられている。【選択図】図5
