IMPACT ABSORBING STRUCTURE FOR VEHICLE

To allow an energy absorbing effect to be reliably exerted upon a side collision by reinforcing the strength of a part between ridge lines in a corrugated plate shape of an impact absorbing member and thereby preventing or suppressing the collapsing deformation of the ridge lines in a corrugated plate from a vehicle width direction.SOLUTION: In an impact absorbing structure for a vehicle, an impact absorbing member 22 is disposed, as a structure for absorbing energy upon a side collision of the vehicle, within a side sill member formed into a hollow shape in a vehicle front-rear direction. The impact absorbing member 22 is formed into a corrugated plate shape and disposed in the vehicle front-rear direction. In the corrugated plate shape, parts between ridge lines 24a and 24b and between ridge lines 24c and 24d disposed in the vehicle front-rear direction are each provided with reinforcing means (a first bead 36) for preventing or suppressing the collapsing deformation of the ridge lines 24a, 24b, 24c, and 24d in the vehicle front-rear direction.SELECTED DRAWING: Figure 3 【課題】衝撃吸収部材の波板形状の稜線間の強度を補強することにより、波板の稜線の車幅方向からの倒れ変形を阻止ないし抑制して、側突時のエネルギ吸収作用を確実に行わせる。【解決手段】車両用衝撃吸収構造は、車両前後方向に中空形状に形成されるサイドシル部材内に衝撃吸収部材２２が、車両の側突時にエネルギ吸収作用をする構成として配設されている。衝撃吸収部材２２は車両前後方向に波板形状に形成されて配設されている。波板形状は車両前後方向に配設される稜線２４ａと２４ｂ間、及び稜線２４ｃと２４ｄ間に当該稜線２４ａ、２４ｂ、２４ｃ、２４ｄが車両前後方向へ倒れ変形するのを阻止ないし抑制する補強手段（第１のビード３６）が設けられている。【選択図】図３
