To prevent deformation of a vehicle body frame caused by load input from an axle.SOLUTION: A first reinforcement member 16 is an L-shaped cross section having: a first reinforcing lower plate part 18 superposed on the upper surface of a load input part 10 of a frame lower plate part 8; and a first reinforcing side plate part 19 that is bent from one end-edge part of the first reinforcing lower plate part 18 to extend upward, and superposed on a frame side plate part 6. A second reinforcement member 17 is an L-shaped cross section having: a second reinforcing lower plate part 20 superposed on the upper surface of the first reinforcing lower plate part 18 above the load input part 10; and a second reinforcing side plate part 21 that is bent from one end-edge part of the second reinforcing lower plate part 20 to extend upward, and superposed on the first reinforcing side plate part 19. At a bent part 22 between the second reinforcing lower plate part 20 and the second reinforcing side plate part 21, a rib 23 to be swollen toward the inside of the L shape is formed. At the one side and the other side of the end-edge parts in a longitudinal direction of the first reinforcing side plate part 19, a linear or curved inclined edge part 24 to be inclined so as to separate from each other downward is formed.SELECTED DRAWING: Figure 4 【課題】アクスルからの荷重入力による車体フレームの変形を防止する。【解決手段】第１補強部材１６は、フレーム下板部８の荷重入力部１０の上面に重なる第１補強下板部１８と、第１補強下板部１８の一端縁部から曲折して上方へ延び、フレーム側板部６に重なる第１補強側板部１９とを有するＬ形状断面である。第２補強部材１７は、荷重入力部１０の上方で第１補強下板部１８の上面に重なる第２補強下板部２０と、第２補強下板部２０の一端縁部から曲折して上方へ延び、第１補強側板部１９に重なる第２補強側板部２１とを有するＬ形状断面である。第２補強下板部２０と第２補強側板部２１との間の曲折部２２には、Ｌ形状の内側へ膨出するリブ２３が形成されている。第１補強側板部１９の長手方向の一側及び他側の端縁部には、下方に向かって互いに離間するように傾斜する直線状又は曲線状の傾斜縁部２４が形成されている。【選択図】図４
