PROBLEM TO BE SOLVED: To change a generated load in multistages in response to the magnitude of inputted impact force in an impact absorbing member composed like a lattice by ribs of a honeycomb structure or the like.;SOLUTION: In the impact absorbing member 1, a lattice part 4 formed like a lattice by longitudinally and transversely crossing longitudinal ribs and transverse ribs 3 by a molding die, and a base 5 covering its one face are integrally formed. A wall face height of the longitudinal rib 2 is vertically changed, and in correspondence, a cutout 7 is provided on the transverse rib 3 to partially change its height. By this, height is varied in cross parts 6, and the numbers of the ribs and the cross parts 6 involved in buckling deformation are changed in response to the magnitude of impact. By this, in low impact, G of impact absorption is reduced, and G is enlarged in high impact.;COPYRIGHT: (C)2006,JPO&NCIPI
