ABSTRACT:
The invention provides a vehicular shock absorbing body which absorbs a shock by a grid-like rib formed on a support plate portion and can inhibit a load point at an initial stage and a terminal stage, in a load—displacement (F-S) curve of the vehicular shock absorbing body. A shock absorbing body (40) used for absorbing a shock in a vehicle and made of a synthetic resin, is provided with a support plate portion (42), and a shock absorbing portion (45) formed in a grid shape on the support plate portion (42) by a plurality of thin ribs (44, 44), and plastically deforming at a time of applying a shock load so as to be absorbable a shock energy. A notch (a leading end side notch)48is formed between grid crossing points (46) in the thin rib (44) from a leading end side, and a notch (a root side notch)50is formed from a root side of the grid crossing points (46) so as to include the support plate portion (42), thereby inhibiting a load point from being generated at an initial stage and a terminal stage in the F-S curve.
