(Example 3)
In this example, when three people are seated side by side in the left-right direction with respect to the rear seat, the air-conditioning air A from the sub outlet 42 is devised to avoid a direct hit on the passenger seated in the middle.
In this example, as shown in FIG. 10, in the right duct 3R and the sub duct 32 of the left duct 3L shown in the first embodiment, a plurality of sub outlets 42 are provided in the front-rear direction of the sub duct 32 in the right duct 3R. The position and the position where the plurality of sub outlets 42 are provided in the left duct 3L in the front-rear direction of the sub-duct 32 are alternately shifted in the front-rear direction. The plurality of sub outlets 42 are arranged in a staggered manner in the left and right sub ducts 32.

Thus, as shown in FIG. 11, when the air-conditioning air A is blown out from the plurality of sub-outlets 42, the air-conditioning air A blown out from the left and right sub-outlets 42 does not collide at the center in the left-right direction of the vehicle. , Can pass in the left-right direction. Therefore, it is possible to prevent the air-conditioning air A blown out from the left and right sub outlets 42 from colliding at the center in the left-right direction of the vehicle and hitting the occupant sitting in the middle of the left-right direction of the seat. .

Therefore, according to the duct 3 of this example, the air-conditioning air A blown out from the left and right sub blowout ports 42 can form a space in which a slight wind flow is felt over substantially the entire area of the rear seat.
Also in this example, other configurations are the same as those of the first embodiment, and the same effects as those of the first embodiment can be obtained.
