PROBLEM TO BE SOLVED: To reduce the number of part items of a humidifying/dehumidifying device and reduce manufacturing cost. SOLUTION: One blowing fan 5 is arranged at the upstream side of a humidifying/dehumidifying rotor 6 for blowing an air to first and second passages 3A, 3B. First and second change-over doors 11, 12 are provided between each of the first and second passage 3A, 3B and each of an outer blow port 3d and an inner blow port 3c. When the first change-over door 11 communicates the first passage 3A with the outer blow port 3d and shuts it off from the inner blow port 3c, the second change-over door 12 shuts off the second passage 3B from the outer blow port 3d and communicates it with the inner blow port 3c. When the first change-over door 11 shuts off the first passage 3A from the outer blow port 3d and communicates it with the inner blow port 3c, the second change-over door 12 communicates the second passage 3B with the outer blow port 3d and shuts it off from the inner blow port 3c. |
