STABILIZER

摘要

PURPOSE:To enable an arm to be welded integrally and easily produced with sufficient resistance to bending fatigue in a stabilizer used for vehicles or the like by dividing a portion of the arm connected to a main body receiving torsional moment. CONSTITUTION:When a stabilizer 2 is constituted from a main body 2a and arms 2b connected to both ends of said body 2a and having eye ends 2d on the ends respectively, a portion of the arm 2b is divided and the divided portions are welded w to each other to unify the arm 2b. Then the welds w are located between the eye end 2d and a position in which the ratio of bending fatigue strength of base metal of the stabilizer 2 to that of the weld w becomes equal to the ratio of bending stress sigma in a bend 2c to that in the weld w. Namely when the diameter of material of the bend 2c is equal to that of the weld w, the weld w is set to a position which meets sigmaw/sigma<=0.76.
