PROBLEM TO BE SOLVED: To provide an air conditioning unit and an air conditioning device for a vehicle, which can distribute conditioned air efficiently, while inhibiting increase in the size of a damper.SOLUTION: The air conditioning unit comprises: a main duct D1; a sub-duct D4 which branches from the main duct D1, and guides air to a foot outlet 24; and a second switching damper 30 provided in the sub-duct D4 at a position facing the main duct D1. The second switching damper 30 includes: a rotatable shaft 31; and a damper body 32 having a guide shroud 33 continuing circumferentially around the rotatable shaft 31. Rotation of the second switching damper 30 around the rotatable shaft 31 causes an end flange 34A at one circumferential end of the damper body 32, to enter and exit the main duct D1. A radial dimension R1 of the end flange 34A is greater than a radial dimension R2 of an end flange 34B provided at the other circumferential end of the guide shroud 33.SELECTED DRAWING: Figure 4

    【課題】ダンパの大型化を抑えつつ、空調風を効率よく分配することのできる空気調和ユニット及び車両用空気調和装置を提供することを目的とする。【解決手段】空気調和ユニットは、メインダクトD1と、メインダクトD1から分岐し、空気をフット吹出口24に導くサブダクトD4と、サブダクトD4においてメインダクトD1に臨む部位に設けられた第二切替ダンパ30と、を備える。第二切替ダンパ30は、回転軸31と、回転軸31回りの周方向に連続する案内シュラウド33を有したダンパ本体32と、を備え、ダンパ本体32の周方向一端の端部フランジ34Aは、第二切替ダンパ30が回転軸31回りに回転することでメインダクトD1内に出没する。端部フランジ34Aの径方向寸法R1は、案内シュラウド33の周方向他端の端部フランジ34Bの径方向寸法R2よりも大きい。【選択図】図4
