調効率が悪かつた。(Problem to be Solved by the Invention) However, in this type of air conditioner, the conditioned air is sent directly from the front of the car through the duct to the front seat side and the rear seat side. The air outlet temperature depends on the temperature adjustment of the air conditioned air on the front seat side, and it was not possible to adjust the temperature only on the rear seat side. Furthermore, air conditioning efficiency was lower on the rear seat side than on the front seat side due to heat loss within the duct.

調和装置を提供することを目的とする。 In view of this, the present invention allows the temperature of the air-conditioned air to be blown to the rear seat side to be adjusted independently from the front seat side, without sacrificing space in the vehicle interior. It is an object of the present invention to provide an air conditioner for a rear seat of an automobile, which further improves air blowing efficiency on the rear seat side.
