To hardly cause fracture at the time of a collision, in a door beam made of aluminum alloy extruded shapes having a closed section structure with a weld metal zone.SOLUTION: A door beam according to the present invention, which is made of aluminum alloy extruded shapes having a closed section structure with a weld metal zone along a longitudinal direction (direction of extrusion), includes a pair of flanges 2 and 3 that are arranged on the inside and outside in a vehicle body width direction, and a pair of webs 4 and 5 for connecting the pair of flanges together. The weld metal zones 6 and 7 are provided in the pair of webs, and positioned near a neutral axis 8 of bending with respect to bending deformation in the vehicle body width direction.SELECTED DRAWING: Figure 1

    【課題】溶着部を有する閉断面構造のアルミニウム合金押出形材からなるドアビームにおいて、衝突時の破断を生じにくくする。【解決手段】本発明に係るドアビームは、長手方向(押出方向)に沿って溶着部を有する閉断面構造のアルミニウム合金押出形材からなり、車体幅方向内側及び外側に配置される一対のフランジ2,3と、前記一対のフランジを接続する一対のウエブ4,5を備え、溶着部6,7が前記一対のウエブに設けられ、かつ車体幅方向への曲げ変形に対する曲げの中立軸8の近傍に位置する。【選択図】図1
