PROBLEM TO BE SOLVED: To obtain a joint structure of frame members of a vehicle body capable of improving a sealing property at a joint part while securing both of mass production and joint rigidity. SOLUTION: A notch part 28 for preventing cracks at the time of press molding is formed at an end outside a folded part, where a top vertical face 22 and an intermediate horizontal face 26 of a rear cross member 12 are crossed with each other, while a step part 30 is formed for narrowing a notch range of the notch part 28. This can secure mass production by preventing cracks, and facilitate sealing of the notch part 28 with a seal material. An intermediate terminal flange part 26A of the intermediate horizontal face 26 extends from a general face 26B as it is, and is spot-welded to a bottom horizontal face 16 of a rear side member 10 at the same height, so as to secure joint rigidity.
