PROBLEM TO BE SOLVED: To provide an air conditioner for a vehicle capable of smoothly blowing air from an air blowing unit to an air distribution unit.SOLUTION: An air conditioner 1 for a vehicle includes: an air blowing unit 10 including an impeller 111 having a plurality of blades 12, and a motor 19 rotatably driving the impeller 111; an air distribution unit 20 having a plurality of blowout ports 24, 25; and a duct unit 30 that connects the air blowing unit 10 and the air distribution unit 20, and has a flow passage 31 of air blown from the air blowing unit 10. A travelling direction D2 of the flow passage 31 is inclined to a suction direction D1 side of the air sucked into the impeller 111 with respect to an axial perpendicular plane P traversing the center of the impeller 111 among axial perpendicular planes perpendicular to the rotation axis O of the motor 19. Further, the blades 12 are twisted so that the rotation phase of an end portion of the impeller 111 on the suction port 17 side precedes the rotation phase of an end portion of the impeller 111 on a side opposite to the suction port 17 side.SELECTED DRAWING: Figure 1

    【課題】送風部から配風部への円滑な送風を可能とする車両用空調装置を提供する。【解決手段】車両用空調装置1は、複数のブレード12を有するインペラ111とインペラ111を回転駆動するモータ19とを有する送風部10と、複数の吹出口24,25を有する配風部20と、送風部10と配風部20とを連結し送風部10から吹出される空気の流路31を有するダクト部30と、を備え、流路31の進行方向D2は、モータ19の回転軸Oに垂直な軸垂直面のうちインペラ111の中央を横断する軸垂直面Pに対してインペラ111に吸込まれる空気の吸込み方向D1側に傾斜しており、かつ、ブレード12は、インペラ111の吸込み口17側の端部の回転位相がインペラ111の吸込み口17側とは反対側の端部の回転位相より先行するよう捻じられている。【選択図】図1
