PROBLEM TO BE SOLVED: To enhance rigidity of a vehicle, with a simple configuration.SOLUTION: A reinforcement structure for vehicle rear part comprises a D pillar 10 joined with a D pillar outer 10a and a D pillar inner 10b, as well as disposed with a shoulder belt anchor. The reinforcement structure is joined respectively with an opening rim 40 including a door opening 2y formed of the D pillar 10; and a roof side rail 30. The reinforcement structure further comprises: a reinforcement 60 extending in a direction that the D pillar 10 extends, and covering at least joining portions of D pillar 10 and opening rim 40. The reinforcement 60 expands toward the D pillar outer 10a on a side close to the roof side rail 30, and has a raised part contacting a surface of the D pillar inner 10b on a side close to a position where the shoulder belt anchor is installed, and adjacent to an attachment hold 10x for the shoulder belt anchor, and formed with a swollen part 63 forming a closed cross-section with the D pillar inner 10b in a vehicle height direction view and a vehicle width direction view.SELECTED DRAWING: Figure 2

    【課題】 簡易な構成にて車体の剛性を向上させる。【解決手段】 Dピラーアウタ10a及びDピラーインナ10bが接合されてなるとともにショルダーベルトアンカが配設されるDピラー10を有し、Dピラー10がドア開口2yを形成する開口縁40及び車体のルーフサイドレール30にそれぞれ接合されてなる車体後部を補強する補強構造であって、少なくともDピラー10及び開口縁40の接合部分を覆うとともに、Dピラー10の延伸方向に沿って延在するリインフォース60を備え、リインフォース60は、ルーフサイドレール30に近接する側でDピラーアウタ10a寄りに膨らむとともに、ショルダーベルトアンカの配設位置に近接する側でDピラーインナ10bの表面に当接する起伏を有し、ショルダーベルトアンカの取付孔10xに隣接して、車高方向視及び車幅方向視にてDピラーインナ10bと閉断面を形成する膨出部63が形成されている、車体後部の補強構造。【選択図】 図2
