摘要： Provided is an automotive rear vehicle body structure which increases the amount of energy that can be absorbed, improves the safety of the vehicle occupant and protects a fuel tank in a reliable manner at the time of a rear end collision while allowing a spare tire to be placed within a cabin. In an automotive rear vehicle body structure having a H-type torsion beam wheel suspension system (12) pivotally supported by side sill extensions (2a, 3a) on either side of the vehicle body, the wheel suspension system including a pair of trailing arms (13, 14) and a torsion beam (15) connecting intermediate parts of the trailing arms with each other, a pair of rear side frames (6, 7) extend rearwardly from side sills (2, 3), and a spare tire pan (10) is defined by downwardly bulging a part of a rear floor panel (11) located between the rear side frames (6, 7). A pair of rear center frames (21, 22) extending in a fore-and-aft direction are located behind the torsion beam (15) and attached to the lower surface of a bottom wall (10a) of the spare tire pan (10).
