For example, it is disclosed in JP-A-57-70627.
As described above, two kinds of resins having different melting points are prepared in advance, first, the housing body having the front grill (horizontal blades) is molded with the resin on the high melting point side, and this housing body is inserted into the assembly molding die. At the same time, by injecting the resin on the low melting point side into the remaining cavity of this mold, a large number of wind direction adjusting blades that are orthogonal to the front grill and whose upper and lower shaft parts are loosely fitted in the shaft hole of the housing body are provided. It is integrally molded in an assembled state in which it is rotatably juxtaposed inside. In this way, one separately formed connecting rod is connected to each airflow direction adjusting blade of the air outlet formed in the assembled state, and the airflow direction adjusting blades rotate in unison in conjunction with the movement of this connecting rod. To change.

The pin 3c is provided between the gripping pieces 4a, 4a, ... Having the notch holes formed at the same intervals as the arrangement intervals of the wind direction adjusting blades 3 in the lengthwise direction of the connecting rod 4. 3c, 3c, ... by press-fitting to fit each blade 3, 3 ,.
And the connecting rod 4 are rotatably connected. As described above, projecting the horizontal rackets 3b and 3b and the pin 3c on the side surface of the wind direction adjusting blade 3 is unavoidable in terms of design in consideration of die cutting. That is, the horizontal brackets 3b, 3b are required to enable the die cutting of the molded product.
b and the pin 3c are projected from the side surface of the wind direction adjusting blade 3, and the parting line PL is set as shown by the two-dot chain line in FIGS. 8 and 9, and the mold is opened in the arrow direction of FIG. This makes it possible to smoothly perform die cutting. According to the above configuration, in the conventional assembly air outlet,
As shown in FIG. 7, horizontal brackets 3b, 3b and pins 3c of the wind direction adjusting vanes 3 are present in the gaps between the wind direction adjusting vanes 3 that are rotatably incorporated into the housing body 1 having the front grill 2 by molding. The structure is such that when viewed from the front, the horizontal brackets 3b, 3b and the pin 3
c and the connecting rod 4 enter the field of view, not only impairing the appearance, but also significantly reducing the blowing efficiency and the environment due to the reduction of the opening area, the increase of ventilation resistance, the generation of wind noise, and the like.

Since the connecting rod, the bracket, the pin, etc. do not exist in the air flow path of the housing main body, the air rectifying effect is enhanced and the blowing efficiency is extremely improved, not to mention the excellent design. In particular, in the present invention, since the structure of the connecting portion with the connecting rod in the wind direction adjusting blade of the assembled molding air outlet is the pin gripping portion having the above-mentioned cutout hole, the mold structure is simplified and the die cutting is performed. It will be easy. Also, wind direction adjustment wings
The lower shaft of the root has a through hole on the housing body
A flange is provided so that it can be sandwiched underneath, and the connecting rod is in the wind direction.
Because it has a flange at the connection with the node blades, it can adjust the wind direction.
The vertical position of the connecting rod at the joint between the blade and the connecting rod.
Prevents misalignment and falling out, and further on the housing body
When the shaft part of the wind direction adjusting blade is molded, the coaxial part shrinks.
To adjust the airflow direction adjustment vanes on the housing body.
On the supporting shaft part and the connecting part between the wind direction adjusting blade and the connecting rod.
Generate an appropriate frictional force, which causes
To adjust the wind direction unless the knob is operated and the operating knob is operated.
The rotation position of the root can be maintained as it is.
