PROBLEM TO BE SOLVED: To prevent enlargement of a device, to promote miniaturization and light weight, and to improve temperature controllability by providing a wind direction adjustment door capable of adjusting the direction of air bypassing a heat radiation heat exchanger in a ventilation flue. SOLUTION: An air mix door 6 adjusting the ratio of the quantity of an air bypassing a heater core and passing through a bypass passage 5, to an air passing the heater core 4 is provided between an evaporator 3 and the heater core 4. A DEF outlet 7, a VENT outlet 8, and a FOOT outlet 9 are provided in the downstream side of a ventilation flue 2 and the respective outlets 7, 8, 9 are opened/closed by dampers 10, 11, 12. The air is jetted from one or a plurality of outlets opened by rotationally moving the dampers 10, 11, 12 according to the respective modes to a compartment. A wind direction adjustment door 13 for adjusting the direction of the air bypassing the heater core 4 and passing the passage 5 is provided in the bypass passage 5 in the ventilation flue 2. The wind direction adjustment door 13 is composed of a turnable door.
