Thus, the air flow goes straight through the ventilation path 6, passes between the rear fin 41 and the front fin 30, and is blown forward from the air outlet 5. At this time, the airflow is squeezed from the upper and lower sides to the center side by the ridges 25 projecting from the upper and lower portions inside the air outlet 5, and the airflow is directed toward the front with good directivity. Is done.

  When the ventilation path 6 is closed and the ventilation is shut off in such a blowing state, the dial operation knob 7 is grasped and rotated, for example, counterclockwise around the axis as shown in FIG. Thereby, the rotational force of the dial operation knob 7 is transmitted to the bevel gear 20 via the universal joint 10, the second spherical body 18, and the universal bearing 23, and the bevel gear 20 rotates. Then, the rotation of the bevel gear 20 is transmitted to the damper device 50, the damper plate 51 rotates in the clockwise direction in FIG. 24B, the peripheral edge of the damper plate 51 abuts against the inner wall of the ventilation path 6, and the ventilation path 6 is closed by the damper device 50.

  On the other hand, when adjusting the blowing direction up or down in the blowing state, the dial operation knob 7 is held and the front fin 30 of the front movable louver 3 is rotated up or down. When the dial operation knob 7 is held and rotated up or down, as shown in FIGS. 23 (b) and 24 (a), the front fins 30 to which the dial operation knob 7 is attached are supported on the support shafts 34 on both sides thereof. As a result, the front fin 30 is tilted obliquely upward or obliquely downward to adjust the blowing direction.
