The present invention provides a technology where components can be easily assembled and reinforced on bending part containing bending positions on a lengthwise shaft. An automobile body frame (11) is provided with a main frame (22) and rear frames (23L, 23R) extending from the main frame (220) backwards. The main frame (22) is manufactured by forming a component spliced by stamped panels into a square tube-shaped stamping frame, and comprises a rectilinear part (27) extending to the rear part of the vehicle in a rectilinear manner; and a bending part (28) which is bent and extends downwards. The rear frames (23) comprise a left and a right rear frames (23L, 23R), the front ends of the rear frames are connected with a left face and a right face in a vehicle width direction of the bending part (28) and extend backwards, and strengthening components (51, 52) are set up in the bending part (28) in a length-direction orthogonal manner with the bending part (28). |
