PURPOSE:To obtain an air-conditioning device wherein a passage resistance is small and a blowing air velocity does not become too large in the case of downward blowing and wherein the blowing air velocity in the case of blowing in the horizontal direction can be varied by an outlet part. CONSTITUTION:On the lower side of a passage 6 in an outlet part, an entrance part 10 at which the width of the passage in the vertical direction is reduced gradually toward the downstream side and of which the longitudinal section parallel to the passage is shaped in a circular arc substantially and an exit part 11 which is connected to the entrance part 10, at which the width of the passage in the vertical direction is widened gradually toward the downstream side and of which the longitudinal section parallel to the passage 6 is shaped in a circular arc substantially, are formed. At the exit end on the upper side of the passage 6 in the outlet part, a projecting part 8 deflecting a part of a flow downward is formed, and the exit part 11 is positioned on the upstream side of the projecting part 8 and forms a single exit together with the projecting part 8. One vane 21 being rotatable in the vertical direction is disposed in a part opposite to the entrance part 10 in the passage 6, while one air-direction deflecting plate 23 being rotatable in the vertical direction is disposed in a part opposite to the exist part 11 in the passage and on the projecting part 8 side of the vane 21. |
