To provide a vehicle frame structure provided with a reinforcement member for securing required strength, while avoiding interference with a brake chamber.SOLUTION: The vehicle frame structure comprises: a side rail 10 with a u-shaped cross section formed of a first side wall part 11, a first upper wall part 13 and a first lower wall part 12; a first reinforcement member 20 with a u-shaped cross section which is smaller in length in a vertical direction of a vehicle than the first side wall part and which is mounted on the inside of the first side wall part; a second reinforcement member 30 with an L-shaped cross section which is smaller in length in the vertical direction of the vehicle than the first side wall part and which is mounted on the outside in a vehicle width direction of the first side wall part; a third reinforcement member 40 with an L-shaped cross section which extends in the vehicle width direction to be connected with the side rail; and a brake chamber 3 of the vehicle arranged below the side rail. In the side rail, a notch part 14 is formed right above, in the vertical direction of the vehicle, the brake chamber, in the first lower wall part, where first to fourth reinforcement members are mounted so that at least portions thereof are positioned right above the notch part.SELECTED DRAWING: Figure 1

    【課題】ブレーキチャンバとの干渉を回避しつつ、必要な強度を確保するための補強部材を設けた車両のフレーム構造を提供する。【解決手段】第1側壁部11と第1上壁部13と第1下壁部12とから形成される断面コの字形状のサイドレール10と、断面コの字形状をなし、車両上下方向の長さが第1側壁部より小さく、第1側壁部の内側に取り付けられる第1補強部材20と、断面L字形状をなし、車両上下方向の長さが第1側壁部より小さく、第1側壁部の車幅方向外側に取り付けられる第2補強部材30と、断面L字形状をなし車幅方向に延在して、サイドレールを接続する第3補強部材40と、サイドレールの下に配置される車両のブレーキチャンバ3と、を備え、サイドレールは、第1下壁部において、ブレーキチャンバの車両上下方向の直上に切欠き部14が形成されており、第1~第4補強部材は、少なくとも一部が切欠き部の直上に位置するように取り付けられる。【選択図】図1
