PROBLEM TO BE SOLVED: To compensate the operation power of a power transmission drive lever in separating an air conditioning door from a position abutting on a seat portion, while avoiding weakening of the operation power of the door, and to avoid an abnormal noise caused by the air conditioning door strongly hitting against the seat portion in closing the door from its opening position. SOLUTION: The power transmission for an air conditioning door is constituted in such a manner that the drive lever 24 is connected to the shaft 14b of the air conditioning door (vent door 14) arranged in the air passage in an air conditioning case 3, to transmit the rotation power to the air conditioning door via the drive lever 24. An energizing force is not provided to the drive lever until the air conditioning door moves to a predetermined position before abutting on the seat portion 21. The energizing force to move the air conditioning door in a direction away from the seat portion 21 is provided to the drive lever from the predetermined position to the position where the door abuts on the seat portion 21. As an energizing means, a coil spring 27 is used. COPYRIGHT: (C)2004,JPO
