Zusammenfassung:	A preform 1050 having edges overlapped and jointed, two outer members 1010, 1020 for forming outer surfaces 1061, 1066 of a hydroformed product 1060, and reinforcement members 1030, 1040 for forming reinforcement ribs 1062, 1067 that divide a hollow cross section of the hydroformed product, including a joint 1055 formed by, when more than three sheet materials for forming the outer members and the reinforcement members are overlapped together, welding a first sheet material 1030 on a surface of the overlapped sheet materials to a second sheet material 1040 positioned inside the first sheet material, and a space disposed and aligned with a joint plane between the second sheet material and a third sheet material 1020 located inside the second sheet material during the welding process.
