To easily perform the fastening work of a bolt when a fitting member is arranged between a member to which the fitting member is fit and a nut.SOLUTION: A side frame 3 has a bolt penetration hole 8 and bracket latching holes 12a, 12b. The bolt penetration hole is formed at a first plate portion 18 of a bracket 10, and a nut 6 is welded to the bracket 10 in such a manner that the nut 6 communicates with the bolt penetration hole. A rear-side latching portion 25 is formed at a third plate portion 20 of the bracket 10. The rear-side latching portion 25 penetrates the bracket latch hole 12b of the side frame 3, is formed into a substantially-L shape extending downward (fastening rotation direction) of a bolt 7 inside in a vehicle width direction rather than the side frame 3, and regulates the movement of the bracket 10 to a direction in which the bracket separates from the side frame 3, a front-and-rear direction, and a downward direction. The bolt 7 is inserted into the bolt penetration hole 8 of the side frame 3 from the inside in the vehicle width direction, and penetrates the bolt penetration hole of the bracket 10 and is fastened to the nut 6.SELECTED DRAWING: Figure 4

    【課題】被取付部材とナットとの間に取付部材が配置される場合のボルトの締結作業を容易に行う。【解決手段】サイドフレーム3は、ボルト挿通孔8とブラケット係止孔12a,12bとを有する。ブラケット10の第1板部18には、ボルト挿通孔が形成され、ボルト挿通孔と連通するようにナット6が溶着される。ブラケット10の第3板部20には、後側係止部25が形成される。後側係止部25は、サイドフレーム3のブラケット係止孔12bを挿通し、サイドフレーム3よりも車幅方向内側でボルト7の下方(締結回転方向)へ延びる略L状に形成され、サイドフレーム3から車幅方向外側へ離間する方向、前後方向、及び下方へのブラケット10の移動を規制する。ボルト7は、サイドフレーム3のボルト挿通孔8に車幅方向内側から挿入され、ブラケット10のボルト挿通孔を挿通してナット6に締結される。【選択図】図4
