PROBLEM TO BE SOLVED: To provide a seal structure which can improve sealability between a substrate and a shaping mold at the time of integral foam molding.SOLUTION: A substrate 10 of a molded article is mounted to a mold surface 2a of a shaping mold 1 where a foam 20 is poured into a mold space 5, and an elastic seal material 30 formed in a hollow cylindrical shape is provided between the substrate 10 and the mold surface 2a. Since the elastic seal material is formed in a hollow cylindrical shape, the elastic seal material is excellent in elasticity. As a result, sufficient elasticity can be exhibited against pressure generated in accordance with foaming of the foam 20 having been poured into the mold space 5, whereby sealability between the substrate 10 and the mold surface 2a of the shaping mold 1 at the time of integral foam molding can be improved. |
