A method for manufacturing a structural member 1, comprises: a first step for inserting a foaming material 103 into a tubular member 102 and holding the foaming material 103 by sandwiching between first and second holding members in the axial direction, and a second step for heating and foaming the foaming material 103 and expanding and deforming a predetermined portion of the tubular member 102 by the foaming pressure of the foaming material 103 in a state where the movement of the first and second holding members in the axial direction is restricted.

    Procédé de fabrication d'un élément structural (1) comprenant : une première étape consistant à insérer un matériau moussant (103) dans un élément tubulaire (102) et à maintenir le matériau moussant (103) en l'intercalant entre des premier et second éléments de maintien dans le sens axial, et une seconde étape destinée à chauffer et faire mousser le matériau moussant (103) et à dilater et déformer une partie prédéterminée de l'élément tubulaire (102) sous l'effet de la pression de moussage du matériau moussant (103), dans un état dans lequel le mouvement des premier et second éléments de maintien dans le sens axial est restreint.

    構造部材1の製造方法は、筒部材102内に発泡材103を挿入すると共に、軸方向において発泡材103を第1,第2保持部材で挟んで保持する第1工程と、第1,第2保持部材の軸方向の移動を規制した状態で、発泡材103を加熱して発泡させ、泡材103の発泡圧で筒部材102の所定部分を拡大変形させる第2工程とを備える。
