Abstract
A car trim including a plurality of ribs formed integrally and arranged vertically at a predetermined interval on a predetermined site of the rear face 1a of trim main body 1 for absorbing energy of collision, each rib being formed in a rectangular tube, each rib side wall 4a being tapared with thinning toward its distal end, and a rigidity changing portion P being disposed by integrally forming an auxiliary rib piece 5 on the rib side wall 4a for introducing buckling transformation of the rib 4 at a predetemined position in the rib side wall 4a. The rib also includes a first energy absorbing portion 5 and a second energy absorbing portion 6 formed in such a multi-stepped manner that the number of rib walls in the former step is different from that number in the latter step. Further, the rib also includes a first auxiliary rib piece 5 extending outside from each corner along one side wall 3, 4 of the rib and a second auxiliary rib piece 6 extending from the distal end of the first auxiliary rib piece 5 onto the other side wall 4, 3 vertically intersecting that first auxiliary rib piece.
