Claims

[Scope of Claim for Utility Model Registration] An outside air inlet that is opened in the direction in which outside air dynamic pressure is applied during driving and introduces outside air, an air box that receives the introduced outside air, and an air box that sends the outside air introduced from the air box to a blower unit. In a vehicle air conditioner, the vehicle air conditioner is equipped with an inside air introduction hole and an inside/outside air switching valve that opens and closes the inside air introduction hole. An open/close valve is provided in the open/close valve, and the open/close valve is provided with a valve when the blower unit is in operation and the dynamic pressure of the introduced outside air is at a predetermined value. A vehicle air conditioner characterized in that a valve control means for opening the on-off valve at the above times is provided.
