PROBLEM TO BE SOLVED: To stably absorb the impact energy at the time of vehicle collision, etc., in accordance with the presumed deformation mode. SOLUTION: A reinforcing member 2 having a flexible part 3 in the form of beads is attached fast to the front surface of a cab under frame 1. Because the flexible part 3 is strongly fixed to the cab under frame 1 by a continuous laser welding, etc., the part 3 is bent in the parts in front of and behind the trace of beads 12, and the part with beads 12 is free of deformation and exfoliation. This can stabilize the deformed condition when an impact force acts on, and absorption of impact energy can be executed effectively. |
