PROBLEM TO BE SOLVED: To provide a door mechanism in which not only sealability at door closing but also controllability of air volume making the opening degree of the door as operation amount are improved in a rotary door which needs controlling air volume by the operation of the opening degree of the door such as a blowout mode door and an air mix door of the automobile air conditioner. SOLUTION: The tip end part of the blowout mode door 5 is formed with an elastic body inclined to the seal surface 54 direction in the door mechanism which is closed by contacting the outer periphery of the blowout mode door 5 to the seal surface provided on the edge of the opening. When the opening degree of the blowout mode door 5 becomes not less than a predetermined one, the tip end part separates from the seal surface behind the part of the outer periphery. Since the rate of change of air volume in the case of small opening degree of the door can be minimized, controllability can be improved. COPYRIGHT: (C)2004,JPO
