A core body consisting of a support plate that is flexible and can be polymerized onto the upper edge of the main body, and an armrest made of a thermoplastic soft synthetic resin material, the upper end of which is fused to the support plate and covers the upper part of the support plate. and a lower end portion is melted to the lower end portion of the main body to bridge the opening of the main body, and the molding method includes a first parison made of a thermoplastic hard synthetic resin material and a thermoplastic resin material. A second parison made of a soft synthetic resin material is heated and melted and extruded into hollow molds. After the molds are closed, compressed air is blown between the two parisons so that the parisons are brought into close contact with the inner wall of the mold to form a core. and after forming a plate of the covering body and opening and taking out the mold,
The two parisons are cut off at both ends where they are in close contact with each other, bent at the thin hinge that is in close contact with each other in the center, and overlapped by the above-mentioned core face-to-face alignment, and the clip portion formed on one side is engaged with the through hole formed on the other side. (first invention);
A first parison made of a hard thermoplastic synthetic resin material and a second parison made of a soft thermoplastic synthetic resin material are respectively heated and melted and placed in a hollow mold. After the mold is closed, compressed air is passed between the parisons. The first parison is used to form a core body and the first valine is used to form a covering body by blowing into the inner wall of the mold, and at the same time, a second valine is formed using the core of the mold in the close contact area of both parisons. A thin-walled hinge is formed by crushing the pariso/, the core body and the covering body are taken out by opening the mold, and the covering body is polymerized and molded by face-to-face contact with the core body. .
