To decrease pressure loss, and obtain a desired rectification effect without increasing the length in the thickness direction of a rectification mechanism.SOLUTION: Provided is a rectification mechanism 26 which is disposed on an air flow downstream side relative to a blower fan 201 out of a case inner passage formed by an air conditioning case 12, and in which rectification passages 2681 and 2682 for rectifying a swirl flow generated by rotation of the blower fan 201 in air blown out from the blower fan are partitioned and formed. Further, in the rectification mechanism 26, a contraction rectification passage 2681 is formed in which a passage area of an outflow port 268b from which rectified air flows out becomes smaller than a passage area of an inflow port 268a into which the swirl flow flows.SELECTED DRAWING: Figure 3

    【課題】圧力損失の低減を図るとともに、整流機構の厚み方向の長さを長くすることなく所望の整流効果を得られるようにする。【解決手段】空調ケース12により形成されたケース内通路のうち送風ファン201に対し空気流れ下流側に配置され、送風ファンから吹き出された空気に送風ファン201の回転によって生じた旋回流を整流する整流通路2681、2682が区画形成された整流機構26と、を備える。そして、整流機構26には、旋回流が流入する流入口268aの流路面積より、整流された空気が流出する流出口268bの流路面積が小さくなる縮小整流通路2681が形成されている。【選択図】図3
