To provide a vehicle body rear section reinforcement structure that can accomplish an efficient placement of a certain component while suppressing an increase in weight and an increase in production costs.SOLUTION: A vehicle body rear section reinforcement structure 1 includes a roof side rail 80, a rear pillar 70, a roof side inner panel 30, and a roof side reinforcement panel 40. A certain component 3 is placed at the rear section of a vehicle body 9 so as to face the roof side inner panel 30 from the internal side in the vehicle widthwise direction. The roof side reinforcement panel 40 extends in the back-and-forth direction at least between the certain component 3 and the rear pillar 70. At least either one of the roof side inner panel 30 and the rear pillar 70 is formed with a convex portion 10 which protrudes inwardly in the vehicle widthwise direction at a location facing the roof side reinforcement panel 40 from the internal side in the vehicle widthwise direction, and which extends in the back-and-forth direction at least between the certain component 3 and the rear pillar 70.SELECTED DRAWING: Figure 4

    【課題】重量増加及び製造コストの高騰を抑制しつつ、特定部品の効率的な配置を実現できる車体後部補強構造を提供する。【解決手段】車体後部補強構造1は、ルーフサイドレール80、リヤピラー70、ルーフサイドインナパネル30及びルーフサイドリンフォースパネル40を備える。車体9の後部には、特定部品3がルーフサイドインナパネル30に車幅方向の内側から対向するように配置される。ルーフサイドリンフォースパネル40は、少なくとも特定部品3とリヤピラー70との間で前後方向に延びている。ルーフサイドインナパネル30及びリヤピラー70の少なくとも一方には、ルーフサイドリンフォースパネル40に車幅方向の内側から対向する位置で車幅方向の内側に突出し、少なくとも特定部品3とリヤピラー70との間で前後方向に延びる凸部10が形成されている。【選択図】図4
