An automobile rear body structure includes a pair of rear side frames extending in a direction longitudinally of a vehicle body and having respective kick-up portions, each of which extends diagonally upwardly and rearwardly to form a bridging portion in a rear wheel zone. A differential unit is disposed substantially between the kick-up portions and a fuel tank is disposed behind the differential unit. A pair of drive shafts for driving respective rear wheels extend transversely from the differential unit and are disposed substantially below the kick-up portions. A medial cross member is interposed between the differential unit and the fuel tank and extends transversely between the paired rear side frames. The cross member has opposite ends connected to the rear side frames at locations immediately behind the kick-up portions. The differential unit is secured to the cross member or a suspension cross member for carrying rear wheel suspension systems. The suspension cross member extends transversely between the rear side frames and is secured to a lower surface of the medial cross member.

An automobile rear body structure comprising: a pair of rear side frames extending in directions to be longitudinal of a vehicle body, each said rear side frame having a diagonally upwardly and rearwardly extending kick-up portion to form a bridge for a respective rear wheel zone; a differential unit disposed substantially between said kick-up portions of said pair of rear side frames; a fuel tank positioned rearwardly of sad differential unit; and means for, in the event of a rear end collision with said rear body structure that tends to push said fuel tank forwardly, substantially avoiding damage to said fuel tank due to contact thereof with said differential unit, said means comprising a medial cross member extending transversely between said pair of rear side frames at a location immediately rearwardly of said differential unit and forwardly of said fuel tank, said differential unit being connected to said medial cross member, said medial cross member having opposite ends connected to respective said rear side frames at locations immediately rearwardly of said kick-up portions thereof, and said fuel tank being mounted to said rear frame members rearwardly of said medial cross member, such that in the event of a rear-end collision said medial cross member is pushed forwardly and thereby moves said differential unit forwardly, thus avoiding contact of the forwardly moving fuel tank with said differential unit.
