Description of the Related Art Conventionally, as a vehicle body rear structure of this type of vehicle, there is one disclosed in Japanese Utility Model Laid-Open No. 63-43084. In such a vehicle body rear structure, a rear suspension support reinforcement panel having a hat-shaped cross section is joined to the vehicle body outer surface of the rear pillar inner panel that constitutes the rear pillar, and a part of the rear pillar inner panel is bulged to the vehicle body outside and the bulging is performed. The projecting part is joined to the rear part of the rear suspension support reinforcement panel.

ている。However, the above-mentioned conventional vehicle body rear structure has the following problems. That is, not only the thrust force directed from the road surface in the vertical direction of the vehicle but also the inclining input directed in the vehicle width direction is always input to the shock absorber mounting portion.
Since the joint surface between the shock absorber bracket and the rear pillar is perpendicular to the vehicle width direction, this inward leaning input acts in the peeling direction with respect to the joint surface, making it weak against peeling.

性が弱い。Further, although a reinforcement panel for supporting the rear suspension is joined to the inside of the rear pillar to reinforce the skeleton, since this reinforced portion is offset with respect to the shock absorber mounting portion,
It cannot be said that it effectively functions as a reinforcement near the local shock absorber attachment site. Moreover,
The rigidity of the vehicle body is weak because the rear pillar and the underfloor are not directly connected to each other by a skeleton member in a cross section taken along a plane perpendicular to the vehicle front-rear direction near the shock absorber attachment site.
