PROBLEM TO BE SOLVED: To provide a vehicle body lower part frame structure capable of efficiently transmitting an input load to a side opposite to an input side, and suppressing folding deformation of a side member, in a front end collision or a rear end collision. SOLUTION: In the vehicle body lower part frame structure, the side member 2 is gently tilted from a rear portion 2Fr of a front side member 2F toward a lower part of a C pillar 3C positioned near a front portion 2Rf of a rear side member 2R, and a rear portion 2Sr of the tilting part 2S is united to the front portion 2Rf of the rear side member 2R. Therefore, the side member 2 has no part largely bending in a vehicular width direction from the front side member 2F to the rear side member 2R. A load inputted due to front end collision or rear end collision is efficiently dispersed to suppress folding deformation of the side member 2. COPYRIGHT: (C)2007,JPO&INPIT
