To provide a frame structure for a vehicle in which a spot gun (electrode) does not interfere with a recess and which has a large impact absorbing capacity.

This frame structure 11 for a vehicle is formed by aligning a second frame member 37 of generally U-shape in cross section with a first frame member 36 of generally U-shape in cross section and closing the gap therebetween. In the first frame member 36, a first recess 43 and a second recess 44 are formed in a first vertical side part 41 and a second vertical side part 42 which face each other, respectively. A bottom side part 48 which forms a crest part 47 is formed by integrally joining a second diagonal side part 46 extending at an obtuse angle α in continuous with the second vertical side part 42 to a first diagonal side part 45 extending at an inner angle of α in continuous with the first vertical side part 41. A third recess 51 is formed at the crest part 47.
