摘要
PROBLEM TO BE SOLVED: To provide a forged suspension arm with suppressed occurrence of a stress corrosion crack.;SOLUTION: Thickness of a first bush press-fitting part 12 and a second bush press-fitting part 13 is maximized by thickness a on a parting line PLin of a part located in an arm part 11 side and thickness a on the parting line PLout of a part located in an opposite side of the arm part 11. Thereby, the concentration of a metal flow caused by forging is avoided, and the density of precipitations is lowered, and an internal stress is also relaxed.;COPYRIGHT: (C)2004,JPO
