た。[Problems to be Solved by the Invention] However, in the above-mentioned conventional air conditioning grill, pressure is applied from a direction perpendicular to the wind direction change deflection which is made of a leaf spring material and is attached in a curved shape. Since the direction of the circular arc is suddenly changed from left to right or right to left all at once, there is a problem that the change in the wind direction is too rapid and lacks smoothness. Further, the shape of the circular arc for guiding the flow of the wind is limited to the fixed circular arc shape determined by the elastic deformation of the wind direction deflecting plate for each of the left and right sides, and there is a problem that the direction of the wind direction adjustment is limited. Moreover, there is also a problem that a parallel link or the like is required to change the direction of the arc of each wind direction deflecting plate and the structure becomes complicated.

Let Z be the intersection of a virtual line Y connecting 16 and the movable shaft 17,
The rear end positions of the respective curved portions 6 are set so that the rotational moments of the joined portions of the rear ends of the curved portions 6 with respect to this intersection Z are substantially the same on both the left and right sides of the same intersection Z. That is, in FIG. 1, the length from the intersection Z to the rear end of each curved portion 6 is
Let L 1 to L 4 be the forces acting on the rear ends of the respective bending portions 6 when the second wind direction deflecting plate 5 is bent, and let F 1 to F 4 be the rotational moments M of the rear ends of the respective bending portions 6 with respect to the intersection point Z. 1 to M 4 are each M 1

Therefore, the rotational moments M 1 to M 4 at the rear ends of the respective curved portions 6 with respect to the intersection Z are balanced on both the left and right sides of the intersection Z.
次に、前記のように構成された本実施例の作用及び効果
を説明する。Next, the operation and effect of this embodiment configured as described above will be described.

入されると、この風Ｗは第２風向偏向板５及び第１風向
偏向板４に沿って順に流れ、送風ダクト１の吹き出し口
Ａから前方へ真直ぐに吹き出される。FIG. 1 shows a state in which the operating knob 15 of the operating member 13 is in the neutral position, and in this state, the respective second wind direction deflecting plates 5 have a free length. Therefore, when the wind W is introduced from the rear of the blower duct 1, the wind W sequentially flows along the second wind direction deflecting plate 5 and the first wind direction deflecting plate 4, and goes straight forward from the outlet A of the blower duct 1. To be blown out.

できる。Next, when the operation member 13 is pressed to the left, for example, about the rotation shaft 16 and rotated in the clockwise direction in FIG. 1, the rotation force is generated by the second connecting wires 18 and 19 to the second connecting wires 18 and 19. Wind direction deflector 5
It is transmitted to the shaft 12 at the rear end. At this time, the distance D 1 between the rotary shaft 16 and the movable shaft 17 in the operating member 13 is set shorter than the distance D 2 between the second airflow direction deflecting plates 5 in the free length, so that the movable shaft 17 is set to the timepiece. As you move around,
The same distance D 2 gradually decreases. Therefore, as shown in FIG. 5, the curved portion 6 of the second wind direction deflecting plate 5 is gradually curved so as to bulge to the right. Therefore, the arcuate shape of the curved portion 6 can be gradually increased or decreased depending on the turning operation amount of the operation member 13, and the direction of the wind flow can be continuously adjusted in both left and right directions. it can.

に流れて吹き出し口Ａから吹き出される。Particularly, in the present embodiment, the distance D 1 is set to about 3/4 of the distance D 2 , so that the rear non-curved portion 8 passes the wind W from the rear of the blower duct 1 regardless of the curved state of the curved portion 6. It is always in the same direction as the direction. Therefore, the wind W introduced from the rear of the air duct 1 smoothly flows along the rear non-bent portion 8 and the curved portion 6 and is blown out from the blowout port A.

複雑な機構を用いることなく連結ワイヤ18,19のみで、
確実かつスムーズに行わせることができる。When the movable shaft 17 moves based on the operation of the operating member 13, the elasticity of the curved portion 6 is increased at the joint portion between the rear end of the curved portion 6 and the rear non-curved portion 8 of the second wind direction deflecting plate 5. Force to resist F 1
.About.F 4 act to generate rotational moments M 1 to M 4 of the operating member 13 with respect to the intersection point Z. In the present embodiment, the position of the rear end of each curved portion 6 and the material and shape of the curved portion 6 are set so that the rotational moments M 1 + M 2 and M 3 + M 4 are the same on both sides of the same movable shaft 17. Therefore, the rotation of the operating member 13 is transmitted in a balanced manner to the second wind direction deflecting plates 5 on both sides thereof. Therefore, the bending operation of each second wind direction deflecting plate 5 can be performed only by the connecting wires 18 and 19 without using a complicated mechanism such as a parallel link.
It can be done reliably and smoothly.

できる。Although not described, when the operating member 13 is rotated in the opposite direction to the above, each second airflow direction deflecting plate 5 is curved so as to bulge to the left. Further, in the air conditioning grill of the present embodiment, the blowing direction of the wind W can be adjusted up and down by rotating the entire inner case 2 up and down with respect to the air duct 1.

ことができる。As described above, the air-conditioning grill of this embodiment has a simple structure and the operation member 13 is operated to operate the second wind direction deflecting plate 5.
The curved portion 6 can be smoothly curved in a balanced manner. Moreover, since the rear non-curved portion 8 is in the same direction as the passage direction of the wind W from the rear of the blower duct 1, the wind W smoothly flows along the second wind direction deflection plate 5, and a particularly strong wind. It is possible to reduce the generation of noise accompanying the blowing of W.
