To improve strength and durability of a joint portion of a bracket and a side frame while reducing weight and cost.SOLUTION: A front flange part 5808 and a rear flange part 5810 of a second mount bracket 58 extend below a lower end part 5804A of a front leg part 5804 and a lower end part 5806A of a rear leg part 5806, respectively, and they are also welded to an outer side surface 2006 of a side frame 20 up to a lower side of the lower end part 5804A of the front leg part 5804 and the lower end part 5806A of the rear leg part 5806. The lower end part 5804A of the front leg part 5804 and a lower end part 5808A on a welded portion of the front flange part 5808 do not match each other in height, and the lower end part 5806A of the rear leg part 5806 and a lower end part 5810A on a welded portion of the rear flange part 5810 also do not match each other in height.SELECTED DRAWING: Figure 4 【課題】軽量化とコスト低減を図りつつ、ブラケットとサイドフレームの接合部分の強度、耐久性の向上を図る。【解決手段】第２マウントブラケット５８の前フランジ部５８０８及び後フランジ部５８１０は、それぞれ前脚部５８０４の下端部５８０４Ａ及び後脚部５８０６の下端部５８０６Ａよりも下方まで延び、前脚部５８０４の下端部５８０４Ａ及び後脚部５８０６の下端部５８０６Ａよりも下方側までサイドフレーム２０の外側面２００６に溶接されている。前脚部５８０４の下端部５８０４Ａと前フランジ部５８０８の溶接箇所の下端部５８０８Ａの高さが一致しておらず、また、後脚部５８０６の下端部５８０６Ａと後フランジ部５８１０の溶接箇所の下端部５８１０Ａの高さが一致していない。【選択図】図４
