Beschreibung
Zusammenfassung:	This structural member for an automobile body has a hollow steel main body having a rectangular cross section. The main body includes a quenched part, a base metal hardness part, and a transition part in this order, in at least a part thereof in an axial direction. The length (L) of the transition part as related to the axial direction satisfies the relationship of 0.006 (mm−1)
