ABSTRACT:
An automotive air conditioning system is disclosed. At the foot mode position of a rotary door25, a gap T is formed along the door diameter between a circumferential end of a door surface25cof the rotary door25and a seal rib28of a case11. The flow path of a foot opening22communicates with a defroster opening20through the gap T. At the defroster mode position of the rotary door25, on the other hand, the other circumferential end of the door surface25ccomes into contact with the seal rib28and closes the gap T, and the door surface25ccloses up the foot opening22. Even upon slight rotation of the foot rotary door under the air pressure of the foot mode, therefore, the defroster blowout air amount and the foot blowout air amount are kept in a predetermined proportion.
