To obtain a vehicle body structure member that is able to decrease an amount of deformation when load is repeatedly input.SOLUTION: In a rear floor side member 20, a projection 98 is provided, as viewed from a plate thickness direction of a vertical rib 66A, on a push-out pin seat 94 side of a vertical rib 66A connecting push-out pin seat 94 on a sidewall part 44 side and a push-out pin seat 96 located inside this push-out pin seat 94. This makes it possible to reinforce the push-out pin seat side 94 of at least the vertical rib 66A, in comparison with the case where a recess is formed, as viewed from the plate thickness direction of the vertical rib 66A, on the push-out pin seat 94 side of the vertical rib 66A and makes it possible to increase the rigidity, on the push-out pin seat 94 side, of at least the vertical rib 66A. Accordingly, deformation of the vertical rib 66A can be prevented, and an amount of deformation of the rear floor side member 20 can be decreased when load is repeatedly input.SELECTED DRAWING: Figure 4
【課題】繰り返し荷重の入力時において変形量を小さく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において、側壁部44側の押出しピン座94と当該押出しピン座94の内側に位置する押出しピン座96とを繋ぐ縦リブ66Aの押出しピン座94側において、縦リブ66Aの板厚方向から見て、凸部98が設けられている。これにより、当該縦リブ66Aの押出しピン座94側において、縦リブ66Aの板厚方向から見て、凹部が形成された場合と比較して、少なくとも縦リブ66Aの押出しピン座94側を補強し、少なくとも縦リブ66Aの押出しピン座94側において剛性を高くすることができる。これにより、当該縦リブ66Aの変形を抑制することができ、繰り返し荷重の入力時においてリアフロアサイドメンバ20の変形量を小さくすることが可能となる。【選択図】図4
