Abstract
An automotive component manufacturing method includes a molding process of pressing a portion of a hollow tube formed from a metal material, or a composite material including a metal and a resin, so as to deform the portion of the hollow tube, from a tube outer side toward a tube inner side, to beyond an axial center of the hollow tube, and mold the portion of the hollow tube into a deformed section deformed with a concave profile; and a deformation process of deforming a location having a high level of residual stress in a closed cross-section configured by the deformed section so as to deform the location out-of-plane.
