To cause a basic cross-sectional shape of a side member performing an energy absorption action to be substantially in the same form and shape, and to reduce costs and a weight without employing a structure reinforced by an additional member.SOLUTION: A side member 12 of a vehicular body like an automobile is placed between a bumper side and a compartment side. A preferential energy absorbing zone X, a subsequent energy absorbing zone Y, and a connection energy absorbing zone S are set for the side member 12. A basic cross-sectional form and shape of the respective zones X, Y and S is formed in substantially the same form and shape. The basic cross-sectional form and shape is a polygonal closed cross-sectional shape, and is a shape having an inward recess. An inward depth of the recess shape is formed so as to be deeper at the subsequent energy absorbing zone Y than that at the preferential energy absorbing zone X. Moreover, a first connection energy absorbing zone S1 is set to have a shorter length in a lengthwise direction than that of a second connection energy absorbing zone S2.SELECTED DRAWING: Figure 4

    【課題】エネルギー吸収作用を行うサイドメンバーの基本的断面形状を実質的に同じ形態形状とするとともに、別部材で補強する構成をとることなく、コスト、重量の軽減を図る。【解決手段】バンパー側と車室側との間に配設される自動車等車体のサイドメンバー12であって、サイドメンバー12には、優先エネルギー吸収ゾーンXと、後続エネルギー吸収ゾーンYと、接続エネルギー吸収ゾーンSが設定される。これら各ゾーンX、Y、Sの基本的断面形態形状は実質的に同じ形態形状とされている。その基本的断面形態形状は多角形形状の閉断面形状で、内方に凹み形状を有する形状である。凹み形状の内方への凹み深さは、優先エネルギー吸収ゾーンXより後続エネルギー吸収ゾーンYの方が深い形成とされている。そして、第1の接続エネルギー吸収ゾーンS1は第2の接続エネルギー吸収ゾーンS2より長手方向の長さが短い設定とされている。【選択図】図4
