PURPOSE:To make it possible to change the air blow-off direction without almost changing the air quantity and to carry out the flow dividing operation which divides the air flow into two directions, that is, a horizontal direction and a downward direction by causing the flow to adhere or to separate to and from a curvature wall according to the rotation of a flow control member. CONSTITUTION:A flow control member 16 which rotates around a rotary shaft 17, comprises a head part 16a of an arcuate shape, the center O of which is eccentric by epsilon and which has a radius of r, a bias operating part 16b, and a branch flow operating part 16c. When a manual lever 10 is at a position other than the branch flow power is supplied to an electromagnet 22, a manual shaft 21 and the rotary shaft 17 are unitarily rotated. Hence, by moving the lever 10, it is possible to set the flow control member 16 at an arbitrary angle, and to carry out the blow-off various patterns such as horizontal blow, downward blow and branch flow. Therefore, since the ratio of upward and downward flows of the control member is changed and deflection of the flow is carried out by use of the adherence effect of the flow to a curvature wall 15, reduction in the air quantity can be almost prevented. |
