The first louver and the second louver having a fixed angle may be used, and the present invention is not limited to other specific configurations.

  As an example, as shown in FIG. 2 (b), a single opening 20 may be provided, a second air outlet 22y may be provided in the center of the vehicle, and sandwiched between a pair of first air outlets 22x. Good. Furthermore, it may be composed of three or more openings, and the number of first louvers and second louvers arranged in the openings may be arbitrary.

  Furthermore, the right sub outlet 14R and the left sub outlet 14L are arranged along the vehicle width direction with the second outlets 20y facing each other closer to the center line CL. The first air outlets 20x may be arranged in a state where the air outlets 20x face each other closer to the center line CL. However, making the second air outlets 20y face each other closer to the center line CL means that air is selectively flowed from the second air outlets 20y between the seats arranged in two rows along the vehicle width direction. It is possible to reduce the possibility that the air flow is hindered, and to more efficiently reduce the temperature unevenness of the in-vehicle environment.
