Zusammenfassung:	To provide a vehicle air conditioner which achieves low ventilation resistance while avoiding enlargement of an air conditioner casing and improvement of cooling performance during maximum cooling.SOLUTION: An upper passage R6a is formed above a heating heat exchanger 4 of an air conditioning casing 2 and a lower passage R6b is formed below the heating heat exchanger 4. A vent passage R4 for supplying conditioned air to an upper half body of an occupant is formed at the upper side of the air conditioning casing 2. An auxiliary heater 5 is provided with cooling air blocking parts 52a, 52b, 52d which inhibit cooling air flowing from the lower passage R6b to the vent passage R4 from flowing to the heating heat exchanger 4 side.SELECTED DRAWING: Figure 5 【課題】空調ケーシングの大型化を回避しながら低通気抵抗化を図り、しかも、最大冷房時の冷房性能を向上させる。【解決手段】空調ケーシング２の加熱用熱交換器４の上方に上側通路Ｒ６ａが形成され、加熱用熱交換器４の下方に下側通路Ｒ６ｂが形成されている。空調ケーシング２の上側には、乗員の上半身に空調風を供給するためのベント通路Ｒ４が形成されている。補助暖房器５には、下側通路Ｒ６ｂからベント通路Ｒ４へ向けて流れる冷風が加熱用熱交換器４側へ流れるのを抑制する冷風遮断部５２ａ、５２ｂ、５２ｄが設けられている。【選択図】図５
