PROBLEM TO BE SOLVED: To provide a vehicle frame structure that can improve EA efficiency at bending deformation and EA efficiency at axial compression deformation by using a single reinforcing member.SOLUTION: A first reinforcing member 30 which forms five vertically-adjacent sub-closed cross sections c in cooperation with a main closed cross section C comprises: a first partitioning wall 36 having a first compression-side partitioning part 36a and a first tension-side partitioning part 36b; and a second partitioning wall 37 having a second compression-side partitioning part 37a and a second tension-side partitioning part 37b. A vertical interval between tension-side ridges 36t, 37t is formed smaller than a vertical interval between compression-side ridges 36s, 37s, and when a load is inputted, a difference between lateral widths of the first and second compression-side partitioning parts 36a, 37a at a front end portion of a front side region 2a and lateral widths of the first and second tension-side partitioning parts 36b, 37b is formed smaller than a difference between lateral widths of the first and second compression-side partitioning parts 36a, 37a at a latter-half portion of the front side region 2a and lateral widths of the first and second tension-side partitioning parts 36b, 37b.SELECTED DRAWING: Figure 6

    【課題】曲げ変形におけるEA効率と軸圧縮変形におけるEA効率とを単一の補強部材で向上することができる車両用フレーム構造を提供する。【解決手段】主閉断面Cと協働して上下に隣り合う5つの副閉断面cを形成する第1補強部材30が、第1圧縮側仕切部36aと第1引張側仕切部36bとを有する第1仕切壁部36と、第2圧縮側仕切部37aと第2引張側仕切部37bとを有する第2仕切壁部37とを備え、引張側稜線部36t,37tの上下間隔が圧縮側稜線部36s,37sの上下間隔よりも小さく形成され、荷重が入力したとき、前側領域2aの前端部分の第1,第2圧縮側仕切部36a,37aの横幅と第1,第2引張側仕切部36b,37bの横幅との差が、前側領域2aの後半部分の第1,第2圧縮側仕切部36a,37aの横幅と第1,第2引張側仕切部36b,37bの横幅との差よりも小さく形成された。【選択図】 図6
