Structural member and structural member for vehicle

A structural member 10 includes a hat member 1 and a closing plate 2. The length LY of the tubular portion formed by the hat member 1 and the closing plate 2 is 6 or more times the height H of a pair of side walls 11 and 12. Each of the side walls 11 and 12 includes a high-strength portion 11A or 12...

Zusammenfassung:	A structural member 10 includes a hat member 1 and a closing plate 2. The length LY of the tubular portion formed by the hat member 1 and the closing plate 2 is 6 or more times the height H of a pair of side walls 11 and 12. Each of the side walls 11 and 12 includes a high-strength portion 11A or 12A and low-strength portions 11B or 12B. The high-strength portion has a yield strength not less than 500 MPa. The low-strength portions have a yield strength of 60 to 85% of that of the high-strength portion. Each high-strength portion extends a distance not less than (⅔)H and not more than 3H as measured in the direction in which the ridges extend, and is provided such that the high-strength portions of the pair of side walls face each other. A pair of low-strength portions sandwich the associated high-strength portion.
