PROBLEM TO BE SOLVED: To reduce projection of a foam layer from a peripheral part of a foam molded article mainly by improving seal properties of end parts of a skin material and a core material.SOLUTION: A bottom seal part 53 is formed by fitting a flange part 51 for sealing provided at an edge part of a skin material 32 to a concavity 52 for sealing provided in the vicinity of a core material 33 so that a tip end part 51a of the flange part 51 for sealing strongly intervenes to a bottom part 52a of the concavity 52 for sealing. A peripheral wall seal part 54 is formed by making an intermediate part of the flange part 51 for sealing warped by strong intervention contact with peripheral wall parts 52b, 52c of the concavity 52 for sealing. The flange part 51 for sealing is pressed to adhere to the peripheral wall part 52c of the concavity 52 for sealing with a form formation pressure of form molding by performing the form molding in this state to form an outer peripheral side seal part 55.SELECTED DRAWING: Figure 3

    【課題】主に、表皮材と芯材の端末部分のシール性を向上させて、発泡成形品の周縁部からの発泡層のハミ出しが低減されるようにする。【解決手段】表皮材32の縁部に設けたシール用フランジ部51を、芯材33の縁部近傍に設けたシール用凹部52へ嵌合して、シール用フランジ部51の先端部51aをシール用凹部52の底部52aに強干渉させることで底部シール部53を形成する。また、強干渉によって反ったシール用フランジ部51の中間部をシール用凹部52の周壁部52b,52cに当接させて周壁シール部54を形成する。この状態で、発泡成形を行って発泡成形の発泡圧でシール用フランジ部51をシール用凹部52の外周壁部52cに圧接させることで、外周側シール部55を形成させる。【選択図】図3
