To provide a vehicular air conditioner configured so that a motor that drives an air blower is cooled utilizing air in a unit introduced by the air blower, which is suppressed from deteriorating in air conditioning efficiency.SOLUTION: A vehicular air conditioner is equipped with a temperature adjusting/blowing part that cools or heats air introduced into a housing and blows the air into a vehicle interior, and an air introducing part that introduces either or both of outside air and the air in the vehicle interior into the housing. The temperature adjusting/blowing part comprises a partition wall partitioning the housing into a first area and a second area, a filter that purifies air passing through the first area and the second area, and a heat exchange part that cools air passing through the filter. The air introducing part comprises a first blowing part that introduces air into the first area, a second blowing part that introduces air into the second area, and a driving part that rotationally-drives the first blowing part and the second blowing part coaxially. The driving part is arranged near the first blowing part, of the first blowing part and the second blowing part and near the first area, of the first area and the second area, which is provided with a driving part cooling passage through air between the filter and the heat exchange part, in the first area is guided to the driving part.SELECTED DRAWING: Figure 1

    【課題】送風機によって導入したユニット内の空気を利用して送風機を駆動するモータを冷却する車両用空調装置において、空調効率の悪化を抑止する。【解決手段】車両用空調装置は、筐体内に導入された空気を冷却又は加熱して車室内に吹き出す温調送風部と前記筐体内に外気と車室内空気の一方又は両方を導入する空気導入部を備え、温調送風部は、筐体内を第1領域と第2領域に仕切る仕切り壁と、第1領域と第2領域を通過する空気を浄化するフィルタと、フィルタを通過した空気を冷却する熱交換部を備え、空気導入部は、第1領域に空気を導入する第1送風部と、第2領域に空気を導入する第2送風部と、第1送風部と第2送風部を同軸にて回転駆動する駆動部を備え、駆動部は、第1送風部と第2送風部のうち第1送風部の側で且つ第1領域と第2領域のうち第1領域の側に配置され、第1領域におけるフィルタと熱交換部の間の空気を駆動部に導く駆動部冷却流路が設けられている。【選択図】図1
