Zusammenfassung:	To provide a method for molding a hollow body by a floating core process, which can easily accommodate a change in the cross-sectional area of a hollow part.SOLUTION: A method for molding a hollow body has the steps of: introducing fused resin into a cavity; solidifying the introduced resin up to a predetermined solidification rate according to a cross-sectional shape of a hollow body to be molded; and allowing the core to pass into the resin prepared to have the predetermined solidification rate.SELECTED DRAWING: Figure 1 【課題】中空部の断面積の変更への対応が容易に行える、フローティングコア方式による中空体の成形方法を提供すること。【解決手段】溶融した樹脂をキャビティの内部に導入する工程と、前記導入された樹脂を、成形すべき中空体の断面形状に応じた所定の固化率となるまで固化させる工程と、前記所定の固化率となっている前記樹脂の内部にコアを通過させる工程と、を有する、中空体の成形方法。【選択図】図１
