Abstract
A preform with edges overlapped and jointed each other and first and second outer members for forming outer surfaces of a hydroformed product, and reinforcement members that are jointed to the first and second outer members to form reinforcement ribs that divide a hollow cross section of the outer surfaces, the reinforcement members having dimensions capable of suppressing elongation in a tensile direction due to a tensile force that develops during hydroforming.
