のに関する。[Detailed Description of the Invention] [Object of the Invention] (Industrial Field of Application) The present invention relates to a method of manufacturing a wind direction adjusting device used for an air outlet for air conditioning or ventilation. This invention relates to a device in which molding of a movable blade rotatably provided within an outer frame and assembly of the movable blade and the outer frame are performed at the same time.
（従来の技術）
従来のこの種の風向調整装置の製造方法として、先に提
案した特公平１−３６７７２号公報に示されている方法
があり、この方法によると、固定羽根を有する外枠内に
回動自在に設けられる可動羽根の成形時に、この可動羽
根と外枠との組立を同時に行なうことができる。(Prior Art) As a conventional method for manufacturing this type of wind direction adjusting device, there is a method shown in Japanese Patent Publication No. 1-36772, which was proposed earlier. When molding the movable blade which is rotatably provided in the mold, the movable blade and the outer frame can be assembled at the same time.

を平面にする必要がある。(Problem to be Solved by the Invention) By the way, in the wind direction adjusting device manufactured by the method disclosed in the above publication, as shown in FIG. A part of the edge of the movable blade 1 crosses a part of the edge of the fixed blade 3 on the frame 2 side, but when molding the movable blade 1, a portion of the edge of the fixed blade 3 is placed on the fixed blade 3. In order to prevent this from occurring, it is necessary to make the opposing surfaces of the two flat.

くしてしまうという問題がある。However, if the facing surfaces of the movable blade 1 and the fixed blade 3 are made flat, when the movable blade 1 is rotated around the shaft 4 formed at both ends, the sides of the flat edges of the movable blade 1 must be Since the corners a and b press the edge of the fixed blade 3 by the dimension C, the operation becomes difficult when the corners a and b of the edge of the movable blade 1 press the edge of the fixed blade 3. , immediately after that, the corners a and b of the edge of the movable blade 1 are connected to the fixed blade 3.
There is a problem that the operation becomes jerky because it comes off the edge of the screen and becomes light to operate.

が悪いという問題がある。In addition, as described above, in order to prevent generation of cracks on the fixed blade 3 when molding the movable blade 1, as shown in FIG. 8 or 9, a part of the edge of the movable blade 1 must be Or you need to make it all flat, but if you do it like this,
In use, the flat parts 5 and 6 of the edges of the movable blade 1 are visible between the fixed blades 3 of the outer frame 2, resulting in a poor appearance.
なお、可動羽根１の縁部の幅ｄを１１程度以下にすると

発生する。Note that if the width d of the edge of the movable blade 1 is set to about 11 or less, the above-mentioned operability problem can be avoided due to shrinkage of the synthetic resin of the movable blade 1 after molding. Separate problems arise in that the material has poor properties and lacks rigidity.

In order to avoid the harmful effect of making part of the edge of the fixed blade 3 on the frame 2 side part of the cavity surface of the mold, that is, to prevent the occurrence of cracks on the fixed blade 3 during molding of the movable blade 1. By making the opposing surfaces of the two planes, the purpose is to prevent jerky operation of the movable blade 1 and to prevent the flat part 5.6 of the edge of the movable blade 1 from being visible during use. It is something.

Since there is a slight gap between each movable blade 21 and the edge of each movable blade 21, there is no problem with the rotation of each movable blade 21, and the end face of the large diameter portion of the shaft 23 of each movable blade 21 is located outside the outer frame 11. wall 1
Since the movable blades 21 are pressed against the end surfaces of the large diameter portions of the central shaft holes 13 of the movable blades 21, appropriate rotational torque is applied to each movable blade 21.

羽根と固定羽根を非接触とすることができ、したがって
、可動羽根の操作力を一定にすることができ、操作がぎ
くしや（することがない。As described above, according to the present invention, when manufacturing the wind direction adjustment device, after assembling and molding the movable blades on the outer frame having the fixed blades, the movable blades are reversed to bring the wind direction adjustment device into use. Therefore, in the use state, the movable blade and the fixed blade can be made non-contact, and therefore, the operating force of the movable blade can be kept constant, and the operation will not be jerky.

Even if there is a flat part or the like in this part, it is not visible to the user, and all the edges of the movable blade visible to the user can be made into curved surfaces, so the appearance is good.
