Abstract

PROBLEM TO BE SOLVED: To weld and fix it to left and right side frames without reducing welding strength of a cross member by forming the side frames as separate bodies by dividing them into main body part members and tip part members, and previously welding the cross member to the tip part members before it is welded to the main body part members. SOLUTION: Left and right side frames 10 and 10 are respectively divided into main body part members 10a and tip part members 10b, and are formed as separate bodies. Taper parts 10c are arranged on the rear ends of the tip part members 10b so that a cross section becomes narrow backward, and bumper facia installing members 10d are arranged in front end parts of the tip part members 10b. Since the left and right tip part members 10b and 10b and a cross member 11 are welded together before a car body frame 15 is formed, installing accuracy of the cross member 11 and a part installed on the cross member can be easily secured. Even if thermal strain is caused in the main body part members 10a and 10a, the thermal strain can be absorbed by adjusting an installing angle by the taper parts 10c and 10c of the left and right tip part members 10b and 10b.
