An automotive air conditioning system is disclosed. At the foot mode position of a rotary door 25, a gap T is formed along the door diameter between a circumferential end of a door surface 25c of the rotary door 25 and a seal rib 28 of a case 11. The flow path of a foot opening 22 communicates with a defroster opening 20 through the gap T. At the defroster mode position of the rotary door 25, on the other hand, the other circumferential end of the door surface 25c comes into contact with the seal rib 28 and closes the gap T, and the door surface 25c closes up the foot opening 22. 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.
