To provide a vehicle body structure member that is disposed on each of left and right sides of a body front part or body rear part and can exert energy absorption performance and rigidity retention performance against not only a collision in a fore-and-aft direction of a vehicle body but also a collision in an oblique direction.SOLUTION: A vehicle body structure member made of a fiber-reinforced resin and disposed at least in either a body front part or a body rear part includes a first member whose content percentage of continuous fibers, which are oriented in a fore-and-aft direction of a vehicle body and a vehicle width direction, out of contained continuous fibers exceeds 50%, and a second member whose content percentage of continuous fibers, which are oriented in a direction tilted leftward or rightward by a predetermined angle from the fore-and-aft direction of the vehicle body, that is, a direction oblique to each of the fore-and-aft direction of the vehicle body and the vehicle width direction, with respect to the contained continuous fibers exceeds 50%. The first member is disposed outside in the vehicle width direction, and the second member is disposed inside in the vehicle width direction. The first member and second member are joined.SELECTED DRAWING: Figure 6
【課題】車体前部又は車体後部の左右両側にそれぞれ設けられ、車体前後方向からの衝突だけでなく斜め方向からの衝突に対してもエネルギ吸収性能及び剛性保持性能を発揮可能な車体構造部材を提供する。【解決手段】車体前部又は車体後部の少なくともいずれかに設けられた繊維強化樹脂製の車体構造部材は、含有する連続繊維のうち、車体前後方向及び車幅方向に沿ってそれぞれ配向する連続繊維の含有比率が50%を超える第1部材と、含有する連続繊維のうち、車体前後方向及び車幅方向それぞれに対して傾斜する方向であって、車体前後方向に対して左右それぞれの方向へ所定角度傾斜した方向に沿って配向する連続繊維の含有比率が50%を超える第2部材と、を含み、第1部材が車幅方向の外側に配置され、第2部材が車幅方向の内側に配置され、第1部材と第2部材とが互いに接合される。【選択図】図6
