PROBLEM TO BE SOLVED: To suppress a peeling load of a pillar in a vehicle.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 trifurcate 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 trifurcate reinforcement 60 is joined with the D pillar 10 at a front flange 60E1 and a rear flange 60E2 interposed between the D pillar outer 10a and the D pillar inner 10b. An inner wall 60a is formed between the front flange 60E1 and the rear flange 60E2, in parallel with or at a sweep-back angle with respect to a vehicle width direction in a vehicle height directional view.SELECTED DRAWING: Figure 3

    【課題】 車体におけるピラーの剥離荷重を抑制する。【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三叉リインフォース60を備え、三叉リインフォース60は、Dピラーアウタ10a及びDピラーインナ10bの間に挟まれる前方フランジ60E1及び後方フランジ60E2にてDピラー10に接合されるとともに、前方フランジ60E1及び後方フランジ60E2の間に、車高方向視において車幅方向に平行又は後退角をなす内壁60aが形成されている、車体後部の補強構造。【選択図】 図3
