摘要： An anti-collision component consisting of a metal hollow profile for automobiles includes a collision side flange, a body side flange, and a web connected to the flanges. The hollow profile has a longitudinal end at which a cross-sectional configuration is deformed by swaging to reduce a dimension between the flanges. The following relations are established: tW>TW RCI≧(tW-TW) where tW is a wall thickness of the web at the end, TW is a wall thickness of the web at a portion where the cross-sectional configuration is not deformed, and RCI is an inside corner radius of a corner formed of the web and each flange at the portion.
