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 for manufacturing an airflow direction adjusting device used for an air outlet for air conditioning or ventilation, and more particularly to a fixed blade. The present invention relates to a molding which simultaneously forms a movable vane rotatably provided in an outer frame and an assembly of the movable vane and the outer frame.
（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 of manufacturing this type of airflow direction adjusting device, there is a method disclosed in Japanese Patent Publication No. 1-36772 previously proposed, and according to this method, an inside of an outer frame having fixed blades is provided. The movable blade and the outer frame can be assembled at the same time when the movable blade that is rotatably provided in the mold is molded.

を平面にする必要がある。(Problems to be solved by the invention) By the way, in the wind direction adjusting device manufactured by the method of the above publication, as shown in FIG. A part of the edge of the movable blade 1 faces a part of the edge of the fixed blade 3 on the frame 2 side in an intersecting manner. In order to prevent the occurrence of the above, it is necessary to make the opposing surfaces of the both flat.

くしてしまうという問題がある。However, if the opposing surfaces of the movable blade 1 and the fixed blade 3 are made flat, when the movable blade 1 is rotated about the shaft 4 formed at both ends thereof, the movable blade 1 has a flat edge portion on both sides. Since the corners a and b press the edge of the fixed blade 3 by the dimension c, the operation becomes heavy 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 fixed to the fixed blade 3.
There is a problem that the operation becomes jerky because the operation becomes lighter than the edge of the.

に発生する。If the width d of the edge of the movable blade 1 is set to about 1 mm or less, the operability problem as described above can be avoided due to the contraction of the synthetic resin of the movable blade 1 after the molding. Separately, the problem of poor performance and insufficient rigidity occurs.

As shown in FIG.
After being turned 180 degrees about 23, the connecting ring portion 32 of the connecting rod 31 as shown in FIG. 4 or the connecting rod as shown in FIG. 5 is attached to the connecting pin 25 of each movable blade 21. When the connecting arc portions 36 of 35 are fitted, the wind direction adjusting device is ready for use.
上述したように、本発明によれば、風向調整装置の製造

ぎくしゃくすることがない。As described above, according to the present invention, when manufacturing the wind direction adjusting device, the wind direction adjusting device is brought into a use state by assembling and forming the movable blade on the outer frame having the fixed blade and then reversing the movable blade. Thus, in the use state, the movable blade and the fixed blade can be brought out of contact with each other, so that the operation force of the movable blade can be made constant and the operation is not jerky.

Even if there is a flat surface or the like in this portion, it is not visible to the user, and the edges of the movable blades visible to the user can all be curved, so that the appearance is good.

法。1. An outer frame having a shaft hole in the inner surface of the opposed outer wall and a fixed blade substantially parallel to the outer wall inside the opposed outer wall having the shaft hole is molded with a synthetic resin. , This outer frame is inserted into the cavity of the mold that uses part of the edge of the fixed blade of this outer frame and the axial hole of the outer wall of this outer frame as part of its cavity surface. Injecting a low melting point synthetic resin that does not have adhesiveness to the synthetic resin of the outer frame, and a part of the edge corresponds to a part of the edge of the fixed blade that is part of the cavity surface. A movable blade that intersects with the fixed blade is formed, and a shaft that is rotatably fitted into a shaft hole of an outer wall that is part of the cavity surface is integrally formed at both ends of the movable blade. After removing the outer frame with blades from the mold The movable blade manufacturing method of wind deflector, characterized in that is inverted about the axis of its ends, which is linked with connecting rod.
