To provide a vehicle body rear section structure for a vehicle capable of securing constraint performance for a crew member by a seat belt by a simple structure even if excessive inertial force is applied to the crew member.SOLUTION: A vehicle body rear section structure for a vehicle includes: a rear pillar 10 that includes an inner panel 11, and an outer panel 12 forming a closed cross-sectional space 14 with the inner panel 11; an anchor portion 20 which is attached to the inner panel 11 and which supports a seat belt; and a reinforcement member 30 which has one end directly joined to the outer panel 12, and another end directly or indirectly joined to the inner panel 11, is disposed at the vehicle rear side relative to the anchor portion 20 in the closed cross-sectional space 14, and reinforces an attachment location of a stay member 2 for supporting opening and closing of a back door relative to the rear pillar 10. When the cross-section of the rear pillar 10 is taken on a plane that includes a tension direction of the seat belt with the anchor portion 20 being as a base point, the one ends and the other ends of the respective another portion 20 and reinforcement member 30 are located on the plane.SELECTED DRAWING: Figure 2
【課題】簡易な構成で、乗員に過大な慣性力が作用した場合でも、シートベルトによる乗員の拘束性能を確保できる車両の車体後部構造を提供する。【解決手段】インナパネル11と、インナパネル11との間に閉断面空間14を形成するアウタパネル12とを有するリヤピラー10と、インナパネル11に取り付けられてシートベルトを支持するアンカー部20と、アウタパネル12に直接的に接合される一端部と、インナパネル11に直接的又は間接的に接合される他端部とを有し、閉断面空間14内においてアンカー部20よりも車両後方側に配置され、リヤピラー10に対するバックドア開閉補助用のステー部材2の取付箇所を補強する補強部材30とを備え、アンカー部20を基点としたシートベルトの引張方向を含んだ平面でリヤピラー10の断面をとったとき、アンカー部20と補強部材30における一端部及び他端部とが前記平面上に位置する。【選択図】図2
