芯材４に各秤表皮材３が加飾されたちのである。(Conventional Extraction Technique) As a conventional automobile interior decoration part, there is one shown in FIG. 6, for example. In this case, a preformed body 1 consisting of a skin material 1a and a core material 1b is molded separately from a base material 2. This base material 2 is formed by integrally molding a core material 4 with a skin material 3 inserted into a mold by injection molding or stamping molding of a thermoplastic resin, or by injection molding of a thermoplastic resin. Each scale skin material 3 is decorated with a core material 4 obtained by stamping molding or paperboard press molding.

という問題があった。(Problem to be Solved by the Invention) However, in such a conventional decorative parts manufacturing method, the base material 2 is created in a separate process completely unrelated to the preform 1, and is assembled afterwards. Therefore, parts are required to attach the hissing member 9 and the like for fixing the base material 2 and the preformed body 1 together. In addition, if the preformed body of the base material 2 is installed in a concave position, the concave portion of the base material 2 should be attached to the preformed body in consideration of variations in the dimensional accuracy of the base material 2 and the preformed body 1.
Therefore, the finished product by assembling the preform 1 to the base material 2 has unevenness in the gap between the base material 2 and the preform 1, resulting in poor appearance. There was a problem.
本発明は、このような従来の問題点に着目してなされた
