The vertical blades 31 are rotatably supported by pivotally attaching a support hole 36 and a shaft 37 to an outer end edge of an outlet (not shown) of an indoor air conditioner extending in a direction perpendicular to the plane of FIG. A plurality of main body portions 40 inside the air outlet are attached to each other by a connecting rod (not shown) that extends in the above direction and engages with the notch 41 while being attached at intervals in the above direction. By reciprocating in the above direction, the blowing direction of the wind is deflected to the left and right of the air outlet. Here, since the rear hard portion 33 is rigid and is fixed at a right angle to the connecting rod via the main body portion 40, and the front hard portion 32 is rotatable but rigid, it follows that the connecting rod reciprocates. The intermediate soft portion 34 is curved in a bow shape as it goes forward (downstream side), and the direction of the blown air is changed to the left and right.

According to the method of manufacturing a vertical blade of claim 3, the mold corresponding to the thick portion of the vertical blade of claim 2 and the mold corresponding to the flexible portion are separately provided and filled in the mold. Before the resin is cured, the mold corresponding to the flexible portion is moved in the resin compression direction to be molded. Since the flexible portion of the vertical blade has a film-like shape and a small thickness, it cannot be filled with the molten resin because it is too narrow in the mold gap. Therefore, the mold of this portion is made a movable separate body, a wide gap is filled with resin, and then this mold is moved in the compression direction before the resin is cured to form a thin film-like flexible portion. . Therefore, the front and rear ends are hard,
Since the middle part is made of soft synthetic resin, compared to conventional vertical blades that required individual molds, individual melting and injection equipment,
Vertical blades consisting of thick-walled parts at both ends and flexible parts in the middle can be molded with a small number of molds and a small amount of work, and the product cost can be reduced by reducing mold cost, equipment cost and labor. .

FIG. 3 shows a method of manufacturing the vertical blade 21 of FIG. The mold for injection molding the vertical blades 21 is, as shown in the figure, an integrated mold 15 on one side and this mold 15
End metal mold 16 facing each other and corresponding to the thick-walled portions 22 and 23 at both ends of the vertical blade, and slidably fitted between the end metal molds 16 and in the middle of the vertical blade. It is composed of an intermediate die 17 corresponding to the flexible portion 24. In this way, the reason why the intermediate mold 17 corresponding to the flexible portion 24 is slidable is that the flexible portion 24
However, since it is film-like and has a small thickness and a large area, the die gap of this thickness is too narrow to fill the molten resin. For example, molten polypropylene 18 is injection-filled into the cavity that is widened by pulling out the intermediate mold 17. Before the polypropylene 18 is hardened, the intermediate mold 17 is moved in the resin compressing direction indicated by the arrow Y until the polypropylene 18 has a predetermined thickness, and a vertical portion composed of thick portions 22 and 23 at both ends and an intermediate flexible portion 24 is formed. The blade 21 is formed.

Since the vertical blades 21 are made of hard polypropylene for both ends 32 and 33 and soft polypropylene for the intermediate portion 34 described with reference to FIG. 4, a separate mold, separate melting and injection equipment are required in the conventional example. In comparison with the above, molding can be performed with a small number of molds and a small amount of work, and the product cost can be reduced by reducing the mold cost, equipment cost, and labor. Further, since the vertical blade of the present invention including the above-described embodiments is made of a single synthetic resin such as polypropylene, it can be recycled more easily than the conventional example of polypropylene of different kinds of hard and soft shown in FIG. There is also an advantage that it is easy.
