PROBLEM TO BE SOLVED: To set an adequate upper/lower air blowing temperature difference in the vertical direction in both a bi-level mode and a foot-defroster mode. SOLUTION: A movable guide member 31 to adjust the mixing degree of hot air and cold air in an air mixing unit 19 is integrally connected to a rotary shaft 28 of an air supply mode door 27. When an air supply mode door 27 is operated to a bi-level mode position, the movable guide member 31 is moved to the rotational position to reduce the mixing degree of hot air and cold air and the upper/lower blowing temperature difference is expanded. On the other hand, when the air supply mode door 27 is operated to the foot-defroster mode position, the movable guide member 31 is moved to the rotational position to increase the mixing degree of hot air and cold air, and the upper/lower blowing temperature difference is reduced thereby.
