To obtain a vehicle body structure member capable of suppressing bending deformation at the time of input of a collision load.SOLUTION: At a branch connection 98 for transferring from a main flow A flowing inside a lateral wall part 44 of a rear floor side member 20 to a branch flow B flowing in a longitudinal rib 78, an extrusion pin seat 94 formed to be thicker than the longitudinal rib 78 is disposed, thereby allowing suppression of fluidity failure. Accordingly, defects of the rear floor side member 20 due to a shrinkage cavity or the like can be prevented, and bending deformation at the time of input of a collision load can be suppressed so that cracking and breakage are prevented.SELECTED DRAWING: Figure 3

    【課題】衝突荷重の入力時に曲げ変形を抑制することが可能な車体構造部材を得る。【解決手段】リアフロアサイドメンバ20の側壁部44内を流れる主流Aから縦リブ78を流れる支流Bへ移行する分岐部98において、当該縦リブ78よりも厚肉に形成された押出しピン座94を設けることによって、湯流れ不良を抑制することが可能となる。これにより、引け巣等によるリアフロアサイドメンバ20の欠陥を防ぎ、衝突荷重の入力時の曲げ変形を抑制し、割れや破断を防ぐことが可能となる。【選択図】図3
