HIGH STRESS STABILIZER FOR VEHICLES

PROBLEM TO BE SOLVED: To obtain a high stress stabilizer for vehicles excellent in durability by prolonging the fatigue life of a bent part. SOLUTION: In the high stress stabilizer 10, the shape of the bent part 16 which is a part most easily broken by being generally loaded with the largest stress is formed in the state where the relationship of 0< ≤4 and ( ×d/R)≤2 is realized when the bending radius in the bent part 16 is expressed by R, the diameter of a base stock before bending by d, the minor axis of the cross section of the bent part 16 by d1, the major axis of the cross section of the bent part 16 by d2 and the flatness rate of the cross section of the bent part 16 by =(d2-d1)/d2. In this way, the stress concentration of shear stress which is generated in the bent part 16 when inputting load is suppressed and the breakage of the high stress stabilizer 10 for vehicles by the stress concentration in this bent part 16 is prevented.
