제1 구성 부재(12) 및 제2 구성 부재(13)에 의해 구성되는 폐쇄된 횡단면 형상을 갖는 자동차용 구조 부재(2)이다. 제1 구성 부재(12)는, 종벽부(12c), 곡부(12b) 및 내향 플랜지(12a)를 가짐과 함께, 곡부(12b)와 제2 구성 부재(13) 사이이며 종벽부(12c)를 제2 구성 부재(13)를 향해 연장한 영역의 적어도 일부의 영역에 형성되어, 곡부(12b) 및 제2 구성 부재(13)를 접합하는 하중 전달부(20)를 갖는다. 이에 의해, 굽힘 압궤 성능을 향상시킬 수 있다.
An automobile structural member (2) has a closed transverse section shape constituted with a first composing member (12) and a second composing member (13). The first composing member (12) has a vertical wall portion (12c), a bent portion (12b), and an inward flange (12a), and has a load transmission portion (20) formed in at least a part of a region being a region between the bent portion (12b) and the second composing member (13) and being a region of an extension of the vertical wall portion (12c) toward the second composing member (13) and which joins the bent portion (12b) and the second composing member (13). Thereby, a bending and crushing performance can be improved.
