In this embodiment, the latching member 103e is shown as a fork, but the latching member 103e can be fixed so that any one vertical baffle can be moved together on the path of the reciprocating movement of the rack gear 103d The shape is not limited thereto.

The rotation of the second rotary knob 103b will be described with reference to FIG. 4. When the second rotary knob 103b is rotated at a predetermined angle (for example, 90 degrees) in the counterclockwise direction, The vertical baffle moves downward together with the rack gear 103d by the latching member 103e.

On the other hand, when the second rotary knob 103b is rotated at a predetermined angle (for example, 90 degrees) along the clockwise direction, the rack gear 103d moves to the upper side in Fig. 4, The vertical baffle moves upward together with the rack gear 103d.

Therefore, the vertical baffle can be diverted in both directions in accordance with the rotational drive of the second rotary knob 103b.

The guide plate 110 includes a first guide gear 113 that rotates about the mount 210 when viewed from the mount 210. The guide plate 110 is disposed on the mount 210 side of the second pivot shaft 200 As shown in FIG.

The first guide gear 113 may be formed in an arcuate shape and the first guide gear 113 may have a plurality of gear teeth 113a on its surface.

The second guide gear 120 may be arranged to engage with the first guide gear 113.

[

7, when the first rotary knob 103a is rotated to the left (for example, 60 degrees with respect to the vertical line C) on the basis of the vertical line C, the first pivot shaft 200 Is rotated in the counterclockwise direction, whereby the first airflow control member 102 is directed upward. At this time, since the second guide gear 120 rotates in a direction opposite to the first guide gear 113, the second pivot shaft 300 rotates in a direction opposite to the first pivot shaft 200.

Therefore, it is possible to form a smooth upward flow along the first airflow control member 102 after the vortex is formed in the air flow guided downward by the second airflow control member 121.

As shown in Fig. 8A, when the first rotary knob 103a rotates to the right in the drawing (for example, it may be 60 degrees with respect to the vertical line C) with reference to the vertical line C, the first pivot shaft 200 is rotated in the clockwise direction as shown in Figs. 5B and 5C, whereby the first airflow control member 102 is directed downward. At this time, since the second guide gear 120 rotates in a direction opposite to the first guide gear 113, the second pivot shaft 300 rotates in a direction opposite to the first pivot shaft 200.

Therefore, it is possible to form a smooth flow downward along the first wind direction control member 102 after a vortex is formed in the air flow guided upward by the second wind direction control member 121. [

When the first rotary knob 103a further rotates in the state of FIG. 8 (for example, it may be 120 degrees based on the vertical line C) as shown in FIG. 9A, the second link The rotation of the second link 132 stops for a predetermined time until the guide groove 111a reaches the bent portion 111b of the guide groove 111a, The protrusion 132a of the second link 132 passes through the bent portion 111b and the protrusion 132a of the second link 132 passes through the bent portion 111b of the guide groove 111a, The first link 131 and the second link 132 are rotated in the counterclockwise direction so that the third link 401 relatively rotated with the curved groove 131a is rotated clockwise.

At this time, the third windshield control member 410 is rotated clockwise along with the third link 401 to completely close the inside of the housing 11. [

This makes it possible to stop the air exhaust operation inside the housing 11. [

Accordingly, the air vent having the multi-stage regulating knob according to the present embodiment has the first, second, and third wind direction control members (not shown) positioned inside the housing 11 only by rotationally driving the two rotary knobs disposed in multi- 102, 121, and 410, the overall size of the air vent can be reduced.
