Description of the Related Art A so-called full air mix type air conditioner configured to blow out air into a vehicle compartment through a blowout port after temperature control has been conventionally known. The air conditioner is disposed in the space below the dash panel and below the dashboard that separates the engine room from the vehicle interior.

Of the air conditioners of this type, the full air mix type air conditioners mounted on passenger cars are generally classified into high class cars, middle class cars and popular cars.

[0004] To briefly describe the respective structures, high-class automobiles often employ a structure in which an air conditioner dedicated to the rear seats is provided in a system different from the air conditioner provided for the front seats. It is often practiced to provide an air conditioner dedicated to the rear seats (hereinafter referred to as a rear seat air conditioner) in the rear trunk room.

As a typical configuration example of the rear seat air conditioner thus arranged, only the refrigerant pipe is provided between the front engine room and the rear trunk room, while only the inside air of the passenger compartment is arranged in the rear seat air conditioner. After being introduced into the interior, the refrigerant is passed through the core of a dedicated evaporator that is piped with a refrigerant to cool it, and then blown out toward the rear seat from a vent provided in a pillar or the like near the rear seat.

Next, the structure of the air conditioner for a middle-class vehicle is, for example, as disclosed in Japanese Utility Model Laid-Open No. 63-66309, for the front seat to blow out the conditioned air to the rear seat. A rear duct extending from the air conditioner to the rear seat is provided, and the inside and outside air conditioned is blown to the rear seat via a center console vent and a rear foot vent provided as a rear seat vent.

In the air conditioner for popular vehicles, only the front seat is subjected to air conditioning to reduce the cost.
