PROBLEM TO BE SOLVED: To provide an air passage adjusting device which prevents doors from being deformed when two doors each being one piece are assembled so as to make the axis of rotation the same.SOLUTION: A rotary shaft 52 of a blowout mode door has a shrunk width part 523 of a cross sectional shape having a length equal to the diameter of a column shape and a width shorter than the length at a portion arranged inside a rotary shaft 42 of an air-mix door. On the other hand, a slit 421, which has a width wider than the shrunk width part 523 and narrower than the length of the shrunk width part 523, is extended in the axis of rotation at a portion where the rotary shaft 52 is arranged inside the rotary shaft 42. |
