A guide pin 5b is inserted and a pin hole 6b is formed in an intermediate portion of the interlocking link 6. An eccentric pin 8a protruding from the upper surface of the dial 8 is inserted into the pin hole 6b from below. ing.
[0036]
As shown in FIG. 2, the dial 8 is formed so that the half circumference has a large diameter and the remaining half circumference has a small diameter, and the upper end of a support shaft 8 c fitted into a boss portion 8 b protruding from the center of the upper surface. Is fitted into a shaft hole 1i formed in the lower surface of the case 1a, so that the dial 8 is rotatably supported by the support shaft 8c. The outer peripheral portion on the large diameter side of the dial 8 is the lower side portion of the finisher 2 The dial 8 is protruded to the front side of the finisher 2 from a long and narrow elongated hole 2d formed on the outer peripheral portion, and the dial 8 can be rotated around the support shaft 8c by rotating the outer peripheral portion with a finger or the like. .
[0037]
The dial 8 has a pin hole 8d formed at a position substantially perpendicular to the eccentric pin 8a with respect to the center of rotation, and a pin 9a projecting from one end of the link 9 is bent into the pin hole 8d. It is fitted from below.
[0038]
The folded link 9 has a structure in which the links 9b and 9c are bent around the pivoting portion 9d by pivoting the ends of a pair of links 9b and 9c formed to have substantially the same length. The shaft pin 10b of the shutter valve 10 protruding from the lower surface of the case 1a is fitted into the pin hole 9e formed on the other end side.
[0039]
The shutter valve 10 has a height substantially equal to the distance between the upper and lower inner surfaces of the case 1a and a length larger than the distance between the left and right inner surfaces of the case 1a. As shown in FIG. It is provided in the center in the vertical direction.
[0040]
The upstream end of the shutter valve 10 is slightly inward of the upstream opening 1b of the case 1a, and the downstream end is brought close to a position where it does not interfere with the front louver 3, thereby reducing the overall length of the case 1a as much as possible.

[0042]
Next, the operation of the thus configured wind direction adjusting device will be described with reference to FIGS.
[0043]
3 and 4 show a state in which air supplied into the case 1a from a duct (not shown) is blown straight forward from the air outlet 2b. At this time, both side inner surfaces of the case 1a and the inclined guide 5 are shown. However, the air flow is not disturbed, as shown in FIG.
[0044]
If it is desired to change the air direction of air from this state, for example, the front louver 3 is rotated upward by holding the knob 3b of the front louver 3, and if it is desired to change downward, the front louver 3 is rotated downward. Thus, it is possible to adjust the air direction of the air blown into the passenger compartment from the air outlet 2b in the vertical direction.
[0045]
Next, when it is desired to change the direction of the air blown out from the air outlet 2b to the left, the dial 8 is rotated clockwise as shown in FIG.
[0046]
As a result, the interlocking link 6 is moved leftward by the eccentric pin 8a of the dial 8, so that the guide pin 5b of the inclined guide 5 is pulled into the guide hole 1h while being pulled by the relief grooves 6a formed at both ends of the interlocking link 6. Therefore, each inclined guide 5 is rotated leftward about the pin 5a as shown in FIG.
[0047]
At the same time, since one link 9b of the half-broken link 9 whose one end is fitted in the pin hole 8d of the dial 8 is moved forward, the other link 9c rotates clockwise around the shaft pins 10a and 10b of the shutter valve 10. The shutter valve 10 is also rotated leftward by the same angle α as that of each inclined guide 5.
[0048]
As a result, of the air flowing through the case 1a, the air hitting the shutter valve 10 is adjusted to the left by the shutter valve 10, and does not hit the shutter valve 10, but extends along the inner surface of the case 1a. The air that has reached the vicinity is blown out from the air outlet 2b because the wind direction is guided to the left by the inclined guide 5 located inside the straight line A connecting the corner portion 1f and the left and right opening edges of the air outlet 2b. While the air is directed leftward, the wind direction in the vertical direction can be adjusted simultaneously by rotating the front louver 3 up and down in this state.
[0049]
When it is desired to change the direction of the air blown from the air outlet 2b to the right, the dial 8 is rotated counterclockwise as shown in FIG.
[0050]
As a result, the interlocking link 6 is moved rightward by the eccentric pin 8a of the dial 8, so that the guide pin 5b of the inclined guide 5 is pulled into the guide hole 1h while being pulled by the relief grooves 6a formed at both ends of the interlocking link 6. Are moved to the right, and each tilt guide 5 is rotated to the right as shown in FIG. 6 around the pin 5a.
[0051]
At the same time, since one link 9b of the half-broken link 9 whose one end is fitted in the pin hole 8d of the dial 8 is moved backward, the other link 9c is counterclockwise around the shaft pins 10a and 10b of the shutter valve 10. The shutter valve 10 is also rotated rightward by the same angle α as that of each inclined guide 5 by being rotated in the rotating direction.
[0052]
As a result, of the air flowing through the case 1a, the air hitting the shutter valve 10 is adjusted in the right direction by the shutter valve 10, and does not hit the shutter valve 10, but extends along the inner surface of the case 1a. Since the air reaching the vicinity is guided in the right direction by the inclined guide 5, the air blown out from the air outlet 2 b is directed rightward, and the front louver 3 is rotated up and down in this state. At the same time, it is possible to adjust the wind direction in the vertical direction.
[0053]
Further, when the dial 8 is further rotated counterclockwise from this state, one side 9b of the middle broken link 9 is further moved rearward, so that the shutter valve 10 is further rotated and the inside of the case 1a is shown in FIG. Since it closes as shown, the air blown out from the air outlet 2b can be blocked.
[0054]
On the other hand, FIG. 8 shows a modified example of the inclined guide 5, and this modified example will be described next.
[0055]
The right and left wind direction adjustment of the air blown out from the air outlet 2b is much more frequent in the right direction than in the left direction because the vehicle has a handle on the right side like a domestic car. In this case, since the driver sits on the right seat, the frequency of adjusting the wind direction toward the driver increases.
[0056]
Therefore, in the modification shown in FIG. 8, a fixed inclined guide 5 is provided on the right side of the opening of the case 1a, and a fixed guide 12 is provided on the left side. The fixed guide 12 rotates the shutter valve 10 counterclockwise. When the wind direction is adjusted to the right direction by rotating in the direction, it is formed in a triangular prism shape having an inclined surface 12a having substantially the same angle as the shutter valve 10, and is adhered to the inner surface of the downstream opening 1c of the case 1a. It is fixed by means.
[0057]
Further, the corner portion 1f of the extended portion 1d provided in the inclined guide 5 is chamfered 1k at substantially the same angle as the inclined surface 12a of the fixed guide 12 in order to reduce the air resistance, and thereby the dial 8 is counterclockwise. By rotating in the turning direction, it is possible to adjust the air direction to the right of the air blown out from the air outlet 2b, and the wind direction controllability is lower than that in the right direction. In addition, it is possible to adjust the wind direction in the left direction, and by making one of the inclined guides 5 a fixed inclined guide and the other fixed guide 12, the interlocking link 6 or the like becomes unnecessary, which simplifies the configuration. The cost associated with this can be reduced.
[0058]
In the above embodiment, the front louver 3 is provided in the horizontal direction and the shutter valve 10 is provided in the vertical direction. However, the front louver 3 may be provided in the vertical direction and the shutter valve 10 may be provided in the horizontal direction. The front louver 3 can adjust the wind direction in the left-right direction, and the shutter valve 10 can adjust the wind direction in the vertical direction.
[0059]
