As shown in Fig. 3, the connecting rods (6R) and (6L) are arranged such that the distance between the support shaft (4) and the connecting pin (5) is such that the inner wind vane is short and the outer wind vane is long. It is arranged obliquely with respect to (3). Therefore, the left wind vane (3
L) and the wind direction vane (3R) on the right part can rotate independently, but the tilt angle of each rotated wind direction vane changes little by little, so that the wind direction can be adjusted more efficiently. .

The above rotating operation can be manually performed as appropriate, but can also be performed electrically. That is, FIG.
As shown in, the motor (11) mounted on the lower rear surface of the air outlet
One end of a crank-shaped turning arm (12) capable of swinging horizontally is fitted to the vertical axis of the and the pin (13a) protruding from the other end
By fitting both ends of the drive connecting arm (14) together with the pin (13b) protruding from the lower end of the center of the wind direction vane (3), the left and right rotation operation of the rotating arm (12) is performed. ) Is transmitted to. It is preferable to provide one motor for the normal linkage (6).

(7) is a connecting arm for connecting the left-side connecting rod (6L) and the right-side connecting rod (6R), both ends of which are bent in a crank shape, and are arranged in the left-right direction (longitudinal direction). ) Is given elasticity, and the shock during operation is alleviated. A right connecting slot (9R) and a left connecting slot (9L) are formed in the longitudinal direction at both ends of the connecting arm (7).

The connecting rods (6R) (6L) and the connecting arm (7) are connected to each other by being heat-tightened at their lower ends. The shape and dimensions of the connecting elongated holes (9R) (9L) are the connecting shafts (8) and (8) when the outlet sides of the right and left wind direction vanes (3R) (3L) are rotated outward. Interferes with the connecting long holes (9R) (9L) and creates wind direction vanes (3L).

Next, the operation will be described. In the wind direction adjusting device having the above configuration, the right and left wind direction vanes can be separately and interlockedly rotated by the connecting rods (6R) (6L). As shown in FIG. 3, the wind vane on the right side
When the outlet side of (3R) faces the outermost side, the connecting shaft on the right side (8)
Is closer to the center side (left end) of the right connecting slot (9R), and when the outlet side of the left wind direction vane (3L) is then directed to the outermost side, the wind direction vane (3L) is shaken out. The left side of the rod (6
The connecting shaft (8) of (L) comes into contact with the most central part (right end) of the left connecting elongated hole (9L), and if it is tried to rotate further outward, the left connecting elongated hole (9L) By pushing the edge of, the outlet side of the rightmost wind vane (3R) inclined to the outermost side is slightly inclined inward, and the inclination angle (A ') becomes smaller than (A), therefore,
The mutual inclination angles (A) + (A ') of the wind vanes of the wind direction device cannot be expanded any further. That is, when the mutual inclination angles of the wind direction vanes of the wind direction device exceed a predetermined angle range, the rotation is limited due to the interference between the wind direction devices. Therefore, the size of the gap distance (a ') between the wind direction vanes in the central portion is maintained at a predetermined value or more set larger than the size of the gap distance (a) of the conventional example, and it is sufficient between the wind direction devices. Since the wind flows, the dew of the wind direction vanes due to the wraparound of the secondary air is prevented.

If you try to turn the outlet side of L) to the innermost side,
Before the (3L) swings off, the connecting shaft (8) of the left connecting rod (6L) contacts the outermost side (left end) of the left connecting elongated hole (9L), and then try to rotate further inward. Then, by pushing the edge of the left connecting elongated hole (9L), the rightmost wind direction vane (3R) tilted inward is slightly tilted outward, and the inclination angle (B ') is more than that of (B). The angle of inclination of the wind direction vanes of the wind direction device
(B) + (B ') cannot be expanded any further. That is, when the mutual inclination angles of the wind direction vanes of the wind direction device exceed a predetermined angle range, the rotation is limited due to the interference between the wind direction devices. Therefore, the size of the gap distance (b ') between the wind direction vanes at the center is equal to the gap distance (b) of the conventional example.
Since the airflow is maintained at a predetermined size larger than the above size, and the airflow sufficiently flows between the airflow direction devices, noise and the like due to the contracted flow can be prevented.

Also in this embodiment, it is possible to manually rotate one of the air flow direction devices (here, the left air flow direction vane) from the state of FIG. 4 to incline to the left as shown in FIG. It is also possible to hold one of the wind direction vanes neutral and rotate the other wind direction vane outward.

(7a) is one connecting pin (5
R) is a shaft-attached connecting arm pivotally connected to the shaft, and is formed in a substantially dogleg shape, and a connecting shaft (8) is projectingly provided at the tip. (7b) is a long hole connecting arm fitted to the other connecting pin (5L), which is formed in a substantially V shape symmetrically with the above-mentioned shafted connecting arm (7a), and has a connecting long hole ( 9) is formed, and the connecting shaft (8) is inserted into the connecting elongated hole (9).

Next, the operation will be described. FIG. 6 (a) is a plan view of a main part when performing normal operation in a neutral state, in which the connecting shaft (8) of the shafted connecting arm (7a) is positioned substantially in the center of the connecting elongated hole (9), When the connecting shaft (8) slides in the connecting elongated hole (9), the left wind direction vane (3L) and the right wind direction vane (3R) are independently rotated. Figure 6
(b) shows the operation in which the right wind vane (3R) and the left wind vane (3L) work together.
When the connecting shaft (8) of (a) abuts the left end of the connecting elongated hole (9) and the angle of one wind direction vane (3) is expanded, the other wind direction vane
(3) is also driven.

In the above embodiment, in order to pivotally connect the shafted connecting arm (7a) and the perforated connecting arm (7b) to the connecting rods (6R) (6L), the connecting pin (5R) of the fin at the opposite position. I used (5L),
