본체(2)는 그 긴 길이 방향의 양단부측에 각각 형성되는 도어 설치부와, 이들 도어 설치부 사이에 배치되는 굽힘 변형 발생부(3)를 갖고, 굽힘 변형 발생부(3)는 홈 저부(4)와 2개의 능선부(5a, 5b)와 2개의 종벽부(6a, 6b)와 2개의 곡선부(7a, 7b)와 2개의 플랜지(8a, 8b)를 갖는다. 홈 저부(4)의 일부에, 도어 임팩트 빔(1)에 작용하는 충격 하중(F)에 대향하도록, 굽힘 변형 발생부(3)의 단면 형상의 외측에 곡면을 갖는 형상으로 돌출되고, 본체(2)의 길이 방향으로 향하여 형성되는 비드(13)를 구비한다.
A main body (2) has door attaching portions respectively formed on both end sides of a long longitudinal direction thereof and a bending deformation generation portion (3) disposed between the door attaching portions, and the bending deformation generation portion (3) has a groove bottom portion (4), two edge line portions (5a, 5b), two vertical wall portions (6a, 6b), two curved portions (7a, 7b), and two flanges (8a, 8b). There is provided a bead (13) which is formed toward the longitudinal direction of the main body (2) in a part of the groove bottom portion (4) in a manner to project in a shape having a curved surface toward the outside of a cross-sectional shape of the bending deformation generation portion (3) so as to oppose an impact load acting on a door impact beam (1).
