PROBLEM TO BE SOLVED: To provide a structure for an air mixing door 5 capable of making an air conditioning unit in a small body without complicating while ensuring sufficient opening areas of a cool air passage 2b and a warm air passage 2c. SOLUTION: The air mixing door 5 is made into a rotary type door, and an evaporator 3 is disposed between a door portion 5a and a rotating fulcrum 5b. Therefore, by placing the rotating fulcrum 5b of the air mixing door 5 at a distant place even without complicating the air conditioning unit 1, a large movable range of the air mixing door 5 can be taken up and the sufficient opening areas of the cool air passage 2b and the warm air passage 2c can be ensured. Furthermore, if rotating, displacement in a radial direction is small, and the evaporator 3 can be stored within the rotating radius, so that the air conditioning unit 1 can be structured in a small body.
