Effect of the Invention As described above, according to the frame structure of an automobile according to the present invention, a plurality of cross members are bridged between a pair of side frames that are formed by raising both sides and having a substantially U-shaped cross section. In the frame structure of an automobile formed as described above, the flange portions are recessed downward to form arcuate receiving portions at predetermined portions of the side surface flange portions facing each other of the side frames, and a cross that is bridged over the portions is formed. An arcuate portion that coincides with the receiving portion is formed at both ends of the member, the arcuate portion is placed on the receiving portion and welded, and the tip of the cross member is abutting surface inside the side surface of the side frame. Since the cross member is welded to and the cross member is connected to the side frame, the stress applied to the connecting portion between the side frame and the cross member can be effectively dispersed. Moreover, since the receiving portion of the side frame is wide, the contact surface is increased and the strength is increased. Further, since the amount of the material itself of the main frame and the cross member is the same as before, the cost is not increased.
