Abstract

PURPOSE: To prevent occurrence of heat distortion and rust in an auxiliary frame due to work of gas cutting or welding, by obliquely forming upward a lower point end part of the auxiliary frame and performing the work of its bending to R.
CONSTITUTION: In a longitudinal side plate portion 5 at the point end part of an auxiliary frame 4 concentrated with the load of a mounted car body 3, a groove shaped part 6 is longitudinally formed by the method of one time press working. Correspondingly to the side plate portion 5 narrowing its width in accordance with the forming of said groove shaped part 6, a lower side point end part 7 is obliquely formed upward to perform work of bending 9 to R. Accordingly, the lower side end part 7 is integrally formed with the auxiliary frame 4 without the necessity for gas cutting or welding work, not caused with heat distortion and rust due to the gas cutting or welding work, capable of holding the strength, fully durable for the load even if concentrated to the point end part of the auxiliary frame 4 further with no suspicion of damage. Further this method being finishable by one time pressing work also requires low cost for manufacture.
