<P>PROBLEM TO BE SOLVED: To reduce a degree that an occupant feels the sound of a blower as noisy. Ž<P>SOLUTION: In a face mode (normal) in which air conditioning air is not blown off from a foot blowing-off port 7, the foot blowing-off port 7 positioned in a location separated further from an ear of the occupant than the position of the inside air suction port 6 is utilized as a suction port of inside cabin air. More specifically, a communication passage 20 communicating a midway portion of a second passage from a foot blowing-off opening 17 to the foot blowing-off port 7 with a portion different from an inside air suction opening 21 out of an air suction side of an air conditioner case 11 is arranged. Further, a first and second doors 31, 32 which selectively open/close the inside air suction opening 21 and the communication passage 20 are arranged. In the face mode (normal), the first door 31 brings the communication passage 20 into an opened state and brings the second passage from the foot blowing-off opening 17 to the foot blowing-off port 7 into a closed state. Also, the second door 32 brings the inside air suction opening 21 into a closed state. Ž<P>COPYRIGHT: (C)2010,JPO&INPIT Ž
