Claims

[Scope of utility model registration request]

When the air mix damper automatically controls the temperature inside the car to the set temperature, in a vehicle air conditioner that uses a mode damper to selectively change the direction of air conditioning air blowing into the car, the air mix damper automatically controls the airflow from the selected blowing direction. An air conditioner for a vehicle, characterized in that a means is provided for fixing the opening of the air mix damper at a predetermined opening level to prevent the conditioned air from exceeding an uncomfortable temperature.
