PROBLEM TO BE SOLVED: To provide a vehicular frame structure capable of improving collision energy absorption performance because it can increase bearing strength against bending deformation of ridge line parts irrespective of a side frame length.SOLUTION: A vehicular frame structure comprises: a front side frame 2; a reinforcement member 30 provided in a closed cross section; and an inner bead part 23c formed by a plurality of ridge line parts 26b, 27b and 28b extending in a vertical direction to a side wall part 23 of the front side frame 2, and protruding to the inside of the closed cross section. The side wall part 23 includes: a front side inclined plane part 23d including a line which connects an upper end part of the intermediate ridge line part 28b and a middle step part of the front side ridge line part 27b; and a rear side inclined plane part 23e including a line which connects the upper end part of the intermediate ridge line part 28b and a middle step part of the rear side ridge line part 26b. The reinforcement member 30 is joined to the front side inclined plane part 23d and the rear side inclined plane part 23e, that is, a front side vicinal part and a rear side vicinal part of the intermediate ridge line part 28b.SELECTED DRAWING: Figure 3
【課題】サイドフレーム長に拘らず稜線部の曲げ変形に対する耐力を増加できるため、衝突エネルギー吸収性能を高くすることができる車両のフレーム構造を提供する。【解決手段】フロントサイドフレーム2と、閉断面内に配設された補強部材30と、フロントサイドフレーム2の側壁部23に上下方向に延びる複数の稜線部26b,27b,28bによって形成され且つ閉断面内側に突出したインナビード部23cとを備え、側壁部23が、中間稜線部28bの上端部と前側稜線部27bの中段部とを結ぶ線を含む前側傾斜平面部23dと、中間稜線部28bの上端部と後側稜線部26bの中段部とを結ぶ線を含む後側傾斜平面部23eとを有し、補強部材30が、前側傾斜平面部23dと後側傾斜平面部23eであって中間稜線部28bの前側近傍部と後側近傍部に接合されている。【選択図】 図3
