摘要

A bumper reinforcing structural unit that can be manufactured at low cost, and provides superior impact resistance in a light weight body. The bumper reinforcing structural unit made of a polymeric resin includes a frame body portion having an upper plate, a lower plate and two end plates for forming an interior space therein. Transverse partition plates divide the interior space of the frame body portion along a longitudinal direction into a central space and two end spaces. A front plate covers the front of the central space, and two back plates cover the back of the end spaces.
