  In such a blowing state, when closing the ventilation path 6 and blocking the blowing, the knob 71 of the dial operation knob 7 is gripped and rotated, for example, counterclockwise around the axis. Thereby, the rotational force of the dial operation knob 7 is transmitted to the bevel gear 20 through the universal joint 10, the sphere 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, and the bevel gear piece 56 and the bevel gear piece 57 on the common shaft 55 rotate in the opposite direction together with the first damper plate 51 and the second damper plate 52. Thus, as shown in FIG. 30, the first damper plate 51 rotates counterclockwise in the figure, the second damper plate 52 rotates clockwise, and the first damper plate 51 and the second damper plate The peripheral edge of 52 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. 29A and 29B, the front fin 30 to which the dial operation knob 7 is attached pivots on the support shafts 34 on both sides thereof. Then, the front fin 30 tilts obliquely upward or obliquely downward, and the blowing direction is adjusted.

  At this time, when the dial operation knob 7 is operated upward or downward and the front fin 30 of the front movable louver 3 is directed upward (obliquely upward) or downward (obliquely downward), FIG. As shown in b), the airflow flowing through the ventilation path 6 is first along the inclined surface 27 on the upstream side of the opposite ridges 25 on both sides inside the air outlet 5 at the front part of the ventilation path 6.

Therefore, the rotational force of the dial operation knob 7 is smoothly transmitted to the bevel gear 20 and the bevel gear 20 rotates.

  Then, the rotation of the bevel gear 20 is transmitted to the damper device 50, and the bevel gear piece 56 and the bevel gear piece 57 on the common shaft 55 rotate in the opposite direction together with the first damper plate 51 and the second damper plate 52.
