To secure the rigidity of a side member in a limited space.SOLUTION: A web outer side surface 10a of a side member 5 has: a notch front area 13 further forward than a notch 12a of an upper flange 11a; a notch corresponding area 14 located at the same position as the notch 12a in a forward and backward direction; and a notch rear area 15 further backward than the notch 12a. A bracket lower portion 18 of a cab mount bracket 8 continuously extends from a front fixed portion 20 which is fixed to the notch front area 13, to a rear fixed portion 21 which is fixed to the notch corresponding area 14. A reinforcing rib 9 is disposed behind the bracket lower portion 18, extends in the forward and backward direction, and is fixed to the web outer side surface 10a. A front end 9a side of the reinforcing rib 9 is disposed further forward than the rear fixed portion 21 of the bracket lower portion 18 and is fixed to the notch corresponding area 14 of the web outer side surface 10a. A rear end 9b side of the reinforcing rib 9 is fixed to the notch rear area 15 of the web outer side surface 10a.SELECTED DRAWING: Figure 4

    【課題】限られたスペースでサイドメンバの剛性を確保する。【解決手段】サイドメンバ5のウェブ外側面10aは、上側のフランジ11aの切欠部12aよりも前方の切欠部前方領域13と、切欠部12aと同じ前後位置に位置する切欠部対応領域14と、切欠部12aよりも後方の切欠部後方領域15とを有する。キャブマウントブラケット8のブラケット下部18は、切欠部前方領域13に固定される前側固定部20から、切欠部対応領域14に固定される後側固定部21まで連続して延びる。補強リブ9は、ブラケット下部18の後方に配置されて前後方向に延び、ウェブ外側面10aに固定される。補強リブ9の前端9a側は、ブラケット下部18の後側固定部21よりも前方に配置され、ウェブ外側面10aの切欠部対応領域14に固定される。補強リブ9の後端9b側は、ウェブ外側面10aの切欠部後方領域15に固定される。【選択図】図4
