性が良好となり、その商品価値が高まるものである。By the way, in the method for manufacturing the skin-integrated headrest, when the foamed resin body 4 is foamed, portions of the horizontally long opening 5 other than the stay insertion portions 7 and 7 and the resin injection portion 8 are each of the above-described portions. The stay insertion portion 7 is closed by the joining members 6, 6.
Is closed by the support rod portion 31 of FIG. Further, the resin injecting portion 8 is brought into close contact with the edge portions 21c and 21d of the peripheral skin material 21 constituting the resin injecting portion 8 by receiving the foaming molding pressure by removing the injecting guide member 9. It is closed by doing. Therefore, when the foamed resin material is foamed, it is reliably prevented that the foamed resin material leaks out of the skin body 2 and adheres to the surface of the skin body 2 to contaminate it. Further, even at the time of injecting the foamed resin material, the fact that the resin injecting nozzle is arranged through the injecting guide member 9 causes a part of the foamed resin material injected from the nozzle to leak to the surface side of the skin 2. Then, it can be reliably prevented from being soiled. Due to these stain-preventing actions, the aesthetics of the headrest 1 as a manufactured product are improved, and its commercial value is enhanced.

とになる。In this embodiment, the horizontally long opening 5 not only functions as an opening for inserting the stay 3 but also serves as an opening for mounting the injection guide member 9 (that is, an opening for resin injection). Therefore, the above-described oblong opening 5 is formed as an opening in the skin 2.
It is sufficient if only the information is provided. Therefore, since the number of openings that affect the aesthetics of the headrest 1 is only one of the horizontally long openings 5, for example, as compared with a configuration in which a stay insertion opening and a resin injection opening are separately provided, for example. The beauty of the headrest 1 is further enhanced.

It is not necessary to dispose a sealing material, which is a separate member, at the stay insertion opening as in the related art. Therefore, in the headrest 1, there is no unevenness due to the interposition of the filler material in the stay insertion portion 7 unlike the related art, and the surface of the stay insertion portion 7 is as smooth as possible. The beauty of the headrest 1 is further improved, and the commercial value of the headrest 1 is further improved.

For example, unlike the conventional manufacturing method, there is no need to prepare a filler material separate from the skin body and to attach the filler material prior to the injection of the foamed resin material, so that the number of required parts is reduced. In addition, the number of working steps can be reduced, the manufacturing cost can be reduced accordingly, and the headrest 1 can be provided at a lower cost.

Further, by removing the stain prevention member 9 from the resin injection portion 8, the edge portions 21c and 21d of the peripheral skin material 21 constituting the resin injection portion 8 receive a foaming molding pressure and adhere to each other. It is closed by doing. Therefore, when the foamed resin material is foamed, it is reliably prevented that the foamed resin material leaks out of the skin body 2 and adheres to the surface of the skin body 2 to contaminate it. Further, even at the time of injecting the foamed resin material, the fact that the resin injecting nozzle is disposed through the fouling prevention member 9 causes a part of the foamed resin material injected from the nozzle to leak to the surface side of the skin 2. Then, it can be reliably prevented from being soiled. By these stain prevention actions,
The beauty of the headrest 1 as a product to be produced is improved, and the commercial value of the headrest 1 is increased.

れることになる。In this embodiment, the lateral opening 5 functions not only as an opening for inserting the stay 3 but also as an opening for injecting resin. It suffices that only the horizontal opening 5 is provided as an opening in 2. Therefore, since the number of openings that affect the aesthetics of the headrest 1 is only one of the horizontally long openings 5, for example, as compared with a configuration in which a stay insertion opening and a resin injection opening are separately provided, for example. The beauty of the headrest 1 is further enhanced.
