PROBLEM TO BE SOLVED: To provide an outlet device capable of increasing more a directivity when air is blown out in a slant direction and assuring a sufficient cover area.SOLUTION: An outlet device comprises a nozzle part 210 for blowing out conditioned air individually toward a task region and a nozzle supporting part 300 for supporting the nozzle 210. The nozzle part 210 has a task air flow passage 230 acting as a cylinder hole passing through the nozzle 210 and it is supported by a pitch axis PX in such a way that it can be inclined. The nozzle supporting part 300 supports the pitch axis PX in such a way that the nozzle part 210 can be inclined in a pitching direction. Further, the nozzle part 210 is supported in such a way that the nozzle part 210 can be rotated around a yaw axis YX perpendicular to a ceiling to which the outlet device is fixed. The task air flow passage 230 has at least one flat plane in parallel with the pitch axis PX at its inner wall surface. For example, the task air flow passage 230 is a prismatic cylindrical hole.SELECTED DRAWING: Figure 4 |
