ABSTRACT:
In a vehicle air conditioner, a link mechanism, for connecting one of plural driving devices and one of plural air mixing doors to each other is connected to a hot water valve, and is constructed to be operated to first and second maximum cooling positions. At the first maximum cooling position, the one door connected to the link mechanism is operated to a door maximum cooling position, and the valve is opened. At the second position, the door connected to the link mechanism is operated to the door maximum cooling position, and the valve is closed. Therefore, the valve can be suitably opened and closed in accordance with operation positions of the plural air mixing doors without using a dedicated driving mechanism for the valve.
