Summary: | To provide a structural member obtained by firmly jointing two high strength steel sheets without weld or mechanical fastening.SOLUTION: A structural member 100 extends in a longitudinal direction L and in which a first member 110 formed of a steel sheet and a second member 120 formed of a steel sheet, are jointed. In the structural member 100, in a cross section vertical to a longitudinal direction L, a closed cross sectional shape is formed by the first and second members 110, 120. The first member 110 has tensile strength of 980 MPa or greater, and first hemming processing parts 111 obtained by performing hemming bending on both end parts in a width direction W orthogonal to the longitudinal direction L. The second member 120 has tensile strength of 980 MPa or greater and has a second adhered part 122a which is held by the first hemming processing parts 111 on both end parts in the width direction W and adhered to the first hemming processing parts 111 by an adhesive 130.SELECTED DRAWING: Figure 1
【課題】溶接または機械的締結なしで2枚の高強度鋼板を強固に接合した構造部材を提供する。【解決手段】構造部材100は、長手方向Lに延び、鋼板製の第1部材110と鋼板製の第2部材120とが接合されている。構造部材100では、長手方向Lに垂直な断面において、第1部材110と第2部材120とによって閉断面形状が構成されている。第1部材110は、引張強度が980MPa以上であり、長手方向Lと直交する幅方向Wの両端部においてヘミング曲げが施された第1ヘミング加工部111を有している。第2部材120は、引張強度が980MPa以上であり、幅方向Wの両端部において、第1ヘミング加工部111に挟み込まれ、第1ヘミング加工部111と接着剤130によって接着された第2被接着部122aを有する。【選択図】図1 |
