Body rear end of a motor vehicle

The rear structure has a cavity formed in the body of a motor vehicle over a rear axis, where the cavity is formed through a vertical through hole (2). The front and back sides of the through hole are bordered by a cross beam (3,4), while the lateral side is bordered by a longitudinal beam (5,6) of the vehicle body. A frame (7) is formed by the beams and closed over the periphery of the through hole.
