PURPOSE:To improve the comfortableness of an entire room by providing a coupling wind direction plate for coupling left and right wind direction regulating plates inside a central wind direction regulating plate divided in a downstream direction from the rotary shaft of the regulating plates. CONSTITUTION:Wind direction regulating plates are divided into a left side wind direction regulating plate 7, a central wind direction regulating plate 8 and a right side wind direction regulating plate 9, and supported by the same rotary shaft 10. The plates 7, 9 are coupled by a coupling wind direction plate 11 inside the plate 8 in a downstream direction from the shaft 10. In this structure, the plates 7, 9 are operated similarly by the plate 11. The plate 8 can be similarly operated to the plates 7, 9 and differently operated from the plates 7, 9 thereby to improve the degree of freedoms of regulating the central and lateral wind directions. For example, when the plates 7, 9 are so directed as to be horizontally blown OFF and the plate 8 is so directed as to be blown OFF slightly downward, the central air can be suppressed by the rightward and leftward airs to increase the arrival of warm air, thereby improving a temperature distribution of a room. |
