PURPOSE:To easily obtain a comfortable air conditioning effect by making it possible to deflect the flow of a wind approximately vertically downward from a horizontal path only with the rotation of a control shaft, while permitting a flow control member to turn within a prescribed region around the control shaft provided with an eccentricity. CONSTITUTION:When a flow control member 10 is turned to such an angle as shown in (a) of the drawing, air blows off horizontally, and when said member is gradually turned counterclockwise, the flow of air is gradually deflected downward, and further when turned to a position shown in (b) of the drawing, it is deflected almost vertically downward. And when it is turned to a position shown in (c) of the drawing, the flow blows off while branching off in both horizontal and downward directions. Accordingly, the flow is arbitrarily directed from horizontal to downward directions with only the rotation of the control member 10 while premitting it to make branch flows. Hereby, by switching the flow to the horizontal direction during air-cooling, to the downward direction during heating and to branching flows when any strong wind is not desired, it is possible to obtain a comfortable air conditioning effect without reducing an air flow. |
