An automotive air conditioner includes a casing, a rotary shaft rotatably supported in the casing, a rotary door connected to the rotary shaft and formed in a substantially arcuate shape, and drive means for rotating the rotary shaft. The rotary door includes a first opening defined by circumferential open ends, and a second opening defined by an arcuate circumferential wall. The casing includes a third opening, a fourth opening, and a fifth opening formed in a downstream end thereof and contiguously arranged along a circumferential surface of the rotary door. Opening areas of the third, fourth and fifth openings are adjusted by the rotary door. When the rotary door is rotated in a direction from the fifth opening toward the third opening and in a predetermined rotated position where one of the circumferential ends of the circumferential wall located at a rear end of the rotary door passes at least part of the fifth opening and opens the fifth opening, an air flows into the second opening and is directed toward the fifth opening through the first opening.
