To provide a vehicular frame structure capable of suppressing a deformation of an entire frame by efficient reinforcement.SOLUTION: A vehicle includes a pair of side members 11 and 12 which extend in a vehicle back-and-forth direction and which are installed side by side with a clearance therebetween in a vehicle widthwise direction. The side members 11 and 12 respectively include: narrow-width portions 11FS and 12FS at the front side; center portions 11C and 12C which are installed at a rear side and which have a wider clearance between the side members 11 and 12 than that of the narrow-wide portions; and boundary portions 11FB and 12FB which are placed between the narrow-width portions and the center portions and which have the above-described clearance gradually becoming widespread toward the rear side. The vehicle includes: a first cross member 40 that interconnects the side members 11 and 12 at rear ends of the boundary portions 11FB and 12FB; and a second cross member 14 that interconnects the side members 11 and 12 at the front side relative to the first cross member 40. Coupling members 41 and 42 that extend in the back-and-forth direction interconnect an intermediate portion of the first cross member 40 in the vehicle widthwise direction and the second cross member 14.SELECTED DRAWING: Figure 2

    【課題】効率良く補強してフレーム全体の変形を抑えることのできる車両のフレーム構造を提供する。【解決手段】車両は、前後方向に延びるとともに車幅方向に間隔を置いて並ぶ一対のサイドメンバ11、12を有する。サイドメンバ11,12は、前方側の幅狭部11FS,12FSと、後方側に配置されてサイドメンバ11,12同士の間隔が幅狭部よりも広い中央部分11C,12Cと、幅狭部および中央部分の間に配置されて上記間隔が後方に向かうに連れて広くなる境界部11FB,12FBとを有する。車両は、境界部11FB,12FBの後端においてサイドメンバ11,12同士を繋ぐ第1クロスメンバ40と、第1クロスメンバ40よりも前方側でサイドメンバ11,12同士を繋ぐ第2クロスメンバ14とを有する。前後方向に延びる連結部材41,42によって、第1クロスメンバ40の車幅方向における中間部分と第2クロスメンバ14とが連結されている。【選択図】図2
