In the ventilation port structure of the air conditioner described above, the air temperature in the left and right direction is unbalanced near the rear seat due to the arrangement of the air outlet 37 and the air inlet 38 on the left and right. That is, the cool air from the outlet 36 is mainly supplied to the right occupant P sitting immediately before the occupant, and is hardly supplied to the left occupant P. Therefore, the left occupant P feels the illuminating feeling of the direct sunlight. Nevertheless, in some cases, the right occupant P may have a problem such as feeling chilly due to excessive cooling.

An object of the present invention is to provide a ventilation port structure of an air conditioner which can realize a comfortable in-vehicle environment by eliminating an imbalance in the ambient temperature of a rear seat.
