PROBLEM TO BE SOLVED: To provide an inside/outside air switching device capable of preventing the occurrence of an abnormal noise due to collision of a partition door with a partition plate or a rotary door.SOLUTION: The inside/outside air switching device includes partition mechanisms 8, 17 capable of partitioning a suction passage 13 into a first suction passage 13a and a second suction passage 13b. The partition mechanisms have the partition door 8 rotatably disposed in a space surrounded by a door surface 42 and a side plate 43 of the rotary door 4, and the partition plate 17 formed in a case 1. A partition door 82 of the partition door body 8 is brought in contact with the partition plate 17 so that the suction passage 13 is partitioned into the first suction passage 13a and the second suction passage 13b. In a recirculation air mode, the partition door body 82 is separated relative to the partition plate 17. In an fresh air mode, the partition door body 82 is separated relative to the partition plate 17. In two-layer flow mode, the partition door body 82 is brought in contact with the partition plate 17. In the partition door body 82, a portion separated from a partition door shaft 81 is connected to the case 1 by a case connection mechanism 9. |
