PURPOSE:To provide means for preventing the stream from adhering to a guide wall when intended to blow off in a horizontal direction, thereby to direct the blow-off angle in the horizontal direction upoward to improve the air conditioning effect. CONSTITUTION:A jet stream A in horizontal blow produces a contracted flow because of a small supply arc-shaped part. For this reason, a clearance is produced between said part and a guide wall 10, and the jet stream A does not adhere to the guide wall 10. Accordingly, the jet stream A blows off in the horizontal direction and it becomes difficult to induce a jet stream B. Therefore, the jet stream B overcomes the force of the jet stream C to blow off horizontally. That is, the air streams blow off horizonatally as a whole. In the case of down-draft, a vane 13 is inclined to direct the air stream toward a direction in which the air stream adheres to the guide wall 10. |
