  • the link member 101 moves up, the vertically dispersing blades 107 pivot upward, and when the link member 101 moves down, the vertical dispersing blades 107 pivot downward. Accordingly, the cool air is dispersed vertically by the vertically dispersing blades 107.
  • the cutout areas of the vertical dispersing blade 107 are smaller than that of the vertically dispersing blade of the third embodiment. Therefore, the cool air is dispersed in vertical direction more efficiently.

Furthermore, the uniform distribution of the cool air can be achieved not only horizontally but also in vertical direction when suitable blades are provided. Since the horizontally dispersing blades are reciprocally rotated in the angular range, the efficiency for dispersing cool air in the horizontal direction is more enhanced.
