To provide a reinforcement structure of a side member which can suppress inward falling of a side member with a simple configuration.SOLUTION: This reinforcement structure comprises: left and right side members 2 having a front part 21 which extends in a vehicle longitudinal direction on a vehicle front side, and a ramp 22 which so extends as to be inclined to a vehicle width direction outer side toward a vehicle rear from the front part 21; a cross member (first cross member 31) which is so located as to be bridged between the front part 21, and has an engine mount 312 which supports an engine 7; and left and right reinforcement members 4 which are so located as to be bridged between the cross member 31 and the ramp 22, and are substantially parallel to the ramp 22 in a vehicle upper surface view. Since the reinforcement structure comprises the reinforcement members 4, a load applied from the front of a vehicle can be transmitted in a longer direction of the side members 2 via the reinforcement members 4, thereby suppressing inward falling of the side members 2.SELECTED DRAWING: Figure 1
【課題】簡易な構成で、サイドメンバの内倒れを抑制できるサイドメンバの補強構造を提供する。【解決手段】車両前方側で車両前後方向に延びる前方部21と、前方部21から車両後方に向かって車幅方向外側へ傾斜しながら延びる傾斜部22とを有する左右のサイドメンバ2と、前方部21間に架け渡されるように配置され、エンジン7を支持するエンジンマウント312を有するクロスメンバ(第一クロスメンバ31)と、クロスメンバ31と傾斜部22との間に架け渡されるように配置され、車両上面視で傾斜部22と略平行である左右の補強部材4とを備える。補強部材4を備えることで、車両前方からかかる荷重を、補強部材4を介してサイドメンバ2の長手方向に伝達することができ、サイドメンバ2の内倒れを抑制できる。【選択図】図1
