ABSTRACT:
A shock absorbing structure for a motor vehicle, including a base plate having a thickness greater than 1.5 mm, and a plurality of ribs formed so as to constitute a latticework on one of opposite major surfaces of the base plate. The latticework has a plurality of rectangular cells each having two pairs of adjacent sides. The ribs have a thickness in a range of 0.6-1.2 mm. One of the two adjacent sides of each cell of the latticework of the ribs has a first length of 30-50 mm, and the other side has a second length greater than 30 mm and not greater than 50 mm. The base plate and ribs are formed of a synthetic resin material comprising polyolefin, which material has an Izod impact strength of not smaller than 5 kgcm/cm, and a tangent modulus of elasticity in a range of 5000-20000 kg/cm.sup.2.
