Abstract
A vehicle front frame structure in which an impact-absorbing extension frame is formed from an inverted U-shaped upper piece overlapping an upright U-shaped lower piece. Because the upper surface of the extension frame is formed only of the U-shaped upper piece, the need for a conventional joined construction is eliminated, thus allowing the upper surface only to be strengthened to provide the optimum desired impact absorbing deformation characteristics.
