To reduce a possibility of a large dust such as a piece of leaf on a filter falling down from the filter when the filter is detached from an air intake housing, in a blower for a vehicular air conditioner operable in a dual-layer-flow mode.SOLUTION: With respect to an internal space of an air intake housing 10, a space above an air inflow surface 51 of a filter 50 is divided by a separation wall 20 into a first space 16A and a second space 16B to which outside air and inside air are respectively taken in in a dual-layer-flow mode. The separation wall 20 has a lower end 23 that divides the air inflow surface into a first region 51A facing the first space and a second region 51B facing the second space. When a side far from a filter insertion hole 15 is referred to as a front, and a side close to the filter insertion hole is referred to as a rear, the first region continuously extends from a front edge 58 to a rear edge 53 of the air inflow surface of the filter, and the second region 51B continuously extends from a front end 55 of the second region to the rear edge 53.SELECTED DRAWING: Figure 4
【課題】二層流モード対応可能な車両用空調装置の送風装置にて、フィルタを空気取入ハウジングから取り外すときにフィルタ上に乗っている木の葉のような大きなダストがフィルタ上から落下する可能性を低下させる。【解決手段】空気取入ハウジング10の内部空間のうちのフィルタ50の空気流入面51よりも上方の空間を二層流モード時に外気と内気とがそれぞれ導入される第1空間16Aと第2空間16Bとに区画する分離壁20の下端23が、空気流入面を、第1空間に面した第1領域51Aと第2空間に面した第2領域51Bとに区画する。フィルタ挿入口15から遠い側を前、近い側を後と呼ぶとしたときに、第1領域は、フィルタの空気流入面の前端縁58から後端縁53まで連続的に延び、第2領域51Bはその前端55から後端縁53まで連続的に延びる。【選択図】図4
