To provide a vehicular frame member that has a longitudinal direction extending in a front-back direction of a vehicle body and is formed in a closed cross sectional shape, which can improve EA mass efficiency with respect to a side collision.SOLUTION: A vehicular frame member 300, which has a longitudinal direction extending in a front-back direction of a vehicle body and is formed in a closed cross sectional shape, comprises: a first side wall 101; a second side wall 102 provided inside in a vehicle width direction with respect to the first side wall; an upper wall 103 and a lower wall 104 defining a closed cross sectional structure together with the first side wall and the second side wall; and an upper vertical rib 107 and lower vertical rib 108, arranged to oppose to the first side wall, which form node parts in the upper wall and the lower wall respectively. When viewed in the longitudinal direction, parts closer to outside in the vehicle width direction than the node parts in the upper wall and the lower wall are provided with reinforcement parts 301 and 302 respectively.SELECTED DRAWING: Figure 9

    【課題】車体前後方向に延びる長手方向を有し、閉断面状に形成された車両用フレーム部材において、側面衝突に対するEA質量効率を向上させる。【解決手段】車体前後方向に延びる長手方向を有し、閉断面状に形成された車両用フレーム部材300は、第1側壁101と、第1側壁に対して車幅方向内側に設けられた第2側壁102と、第1側壁および第2側壁と併せて閉断面構造を画定する上壁103および下壁104と、第1側壁に対向して配置され、上壁および下壁にそれぞれ節部を形成する上側縦リブ107および下側縦リブ108とを備えている。長手方向から見て、上壁および下壁において節部よりも車幅方向外側の部分には、それぞれ補強部301,302が設けられている。【選択図】図9
