PROBLEM TO BE SOLVED: To provide an air outlet port device, capable of switching automatically respective outlet directions utilizing the difference of air volumes between both of ventilations when two kinds of ventilations, different in the air volumes thereof, are supplied selectively such as the warm-air or the cold air, supplied upon heating operation or cooling operation. SOLUTION: The fore opening of lower chamber 32 of a tubular unit 22 in an air outlet port device 10 is used as a warm-air outlet port 34 while the fore opening of upper chamber 30 in the air outlet port device 10 is used as a cold air outlet port 36. A flow resistance unit 38 is provided at the rear part of a partitioning wall 28 so as to permit the passage of warm-air in the small air volume side sufficiently while the resistance unit 38 generates a large flow resistance for the cold air of a large air volume side. A damper 40 for opening and closing the cold air outlet port 36 is provided pivotally in the ceiling part of the upper chamber 30. The damper 40 is opened and closed in accordance with the difference of air volumes between the warm-air and the cold air while the damper 40 is closed by the warm-air and the damper 40 is opened by the cold air.
