調装置。[Scope of Claim for Utility Model Registration] A vehicle air conditioner equipped with a blower unit, an outside air inlet that opens in the direction in which outside air dynamic pressure is applied during driving and introduces outside air, and an intake duct that sends the introduced outside air to the blower unit. In the blower motor control circuit that changes the rotation speed of the blower motor of the blower unit, a dynamic pressure compatible control section that increases the resistance value according to the dynamic pressure of the introduced outside air when the blower motor is operated and reduces the voltage applied to the motor from the power source. A vehicle air conditioner characterized by being provided with.
