The invention relates to a vehicle body frame structure, and aims to improve the rigidity of a vehicle body while ensuring a space under a floor. The vehicle body frame structure is provided with a side beam front part (230) at a joint part (CP1) which is a first joint part, a side beam rear part (240) which is linearly jointed with the vehicle rear end part of the side beam front part (230), and a front part side frame (200) at a joint part (CP2) which is a second joint part and is closer to the vehicle rear side than the joint part (CP1). And a rear side frame (210) linearly coupled to a vehicle rear end portion of the front side frame (200), wherein the front side frame (200) is coupled to the side member front portion (230) and the side member rear portion (240) at a coupling portion (CP1) so as to cover the side member front portion (230) and the side member rear portion (240).
本发明涉及车身框架结构,旨在能够在确保地板下面空间的同时提高车身刚性。所述车身框架结构在作为第一结合部的结合部(CP1)处具备侧梁前部(230),以及与侧梁前部(230)的车辆后方端部直线状地结合的侧梁后部(240),在设置在比结合部(CP1)更靠车辆后方侧的作为第二结合部的结合部(CP2)处具备前部侧框架(200),以及与前部侧框架(200)的车辆后方端部直线状地结合的后部侧框架(210),其中前部侧框架(200)在结合部(CP1)处以覆盖侧梁前部(230)及侧梁后部(240)的方式与侧梁前部(230)及侧梁后部(240)结合。
