PURPOSE:To widely change a flow direction with a compact structure by arranging a plurality of lines of a plurality of a shafts each having rotary blades on a flow passges at a prescribed interval so as to gradually expand from an inlet to an outlet for forming a guide wall. CONSTITUTION:A controller for controlling the direction of a flow blown out of an air conditioner, etc., has a flow passage 7 including an outlet 12 and an inlet 13. In the arragement, a plurality of shafts traversing the passage 7, 8 are provided and these shafts 8 are arranged in a pair at a prescribed interval so as to gradually expand from the inlet 13 to the outlet 12. A rotary blade 9 is provided on each of the shafts 8, while one of the paired rotary blades 9 is rotated by a prescribed angle and respective adjoining rotary blades 9 are superposed one after another. Hereby, guide walls 10, 10a, 11, 11a are constructed. Thus, a flow can be deflected through a plurality of the guide walls 10, 10a, 11, 11a, while it can be widely deflected owing to a Coanda effect. |
