Abstract
In a rear vehicle body structure for a vehicle using a torsion beam suspension system, a laterally extending slot is defined between a vertical front wall of a spare tire pan defined in a rear floor panel and a raised rear end of a front floor panel and a torsion beam of the torsion beam suspension system is received in this slot. The spare tire is received in the spare tire pan in a rear end up slanted orientation. A rear end cross member extends across the vehicle in a rear end of the spare tire pan. In a rear end collision, the spare tire pan is pushed forward by the rear end cross member. The rear end cross member enables the impact load to be evenly distributed to the spare tire pan or the rear floor panel.
