Abstract:
1. A bumper absorber disposed in a bumper system of an automobile, the bumper absorber comprising: an upper side leg portion and a lower side leg portion, each of which extends in a longitudinal direction of the automobile; and a spanning portion connecting the upper side leg portion and the lower side leg portion, and facing an outer surface side of the bumper system in the longitudinal direction of the automobile, wherein at least one leg portion of the upper side leg portion and the lower side leg portion includes a buckling inductive portion, and the buckling inductive portion serves as a starting point of the buckling that is caused in said at least one leg portion when the spanning portion receives an impact load, wherein inner side surfaces, which mutually face between the upper side leg portion and the lower side leg portion of said at least one leg portion including the buckling inductive portion, incline obliquely upward or obliquely downward in the longitudinal direction of the automobile, and the buckling inductive portion is an angular transition portion disposed on said at least one leg portion so that an angle of inclination between the inner side surfaces at a portion from a root of said at least one leg portion to the buckling inductive portion is different from an angle of inclination between the inner side surfaces at a portion from the buckling inductive portion to an end of said at least one leg portion.
