To make it possible to form a three-dimensional shape seen from a press mold direction to be formed inexpensively as a shape capable of press molding without a negative angle.SOLUTION: In a vehicular energy absorption component member 10, first, two planarly shaped parallelogrammic bodies 12 are connected to another planarly shaped parallelogrammic body 12, three faces of a hexagon-forming body viewed three-dimensionally are formed to form a basic structural body 14. Then, a plurality of basic structural bodies 14 are connected and composed to make a basic structural body group 16. In a structural arrangement of the basic structural body group 16, a first summit k where three parallelogrammic bodies 12 of the basic structural body 14 overlap becomes a protrusion (black ○), half of six second summits s in the surroundings formed by the basic structural body 14 overlapping another basic structural body 14 by surrounding a protrusion shape of the first summit k are recesses (○), and a middle part (▵) where the other half becomes middle height of the protrusion and the recesses are arranged by turns, and are arranged in continuous hexagonal lattice shapes.SELECTED DRAWING: Figure 10
【課題】プレス成形方向から見た立方体形状を負角のないプレス成形できる形状として、安価に形成できることを可能とする。【解決手段】車両用エネルギー吸収構成部材10は、先ず、一つの平面形状の平行四辺形体12に他の2つの平面形状の平行四辺形体12が接続されて、立方体形状で見て六角形形成体の三面が形成されて基本構成体14が形成される。そして、この基本構成体14の複数個が連結構成されて基本構成体群16となる。この基本構成体群16の構成配置が、基本構成体14の三つの平行四辺形体12が重なった第1頂点kが凸部(●印)となり、この第1頂点kの凸部形状を囲んで基本構成体14が他の基本構成体14と重なり合うことにより形成される周囲の六つの第2頂点sのうち半分が凹部(〇印)、残り半分が凸部と凹部との中間高さとなる中間部(△印)が交互に配設されて、連続した六方格子状に配置されて成る。【選択図】図10
