PROBLEM TO BE SOLVED: To easily adjust the distance between the rocking centers of ball joints by engaging and fixing the holders of two ball joints and a plurality of irregularities arranged in the longitudinal direction of connecting arms integrally molded with the holders. SOLUTION: Rack-shaped positioning teeth 4 formed in the longitudinal direction of a first connecting arm 5 and a second connecting arm 6 are engaged together, a bolt 7 inserted into an oblong hole is fastened to a nut 8 in this state, and a connecting rod C1 having a pair of ball joints 2, 3 at both ends of a junction 1 is completed. When the distance between the axes, i.e., center distance (d), of balled shanks 22, 32 of the ball joints 2, 3 must be adjusted, the engaging position of the positioning teeth 4 of the first and second connecting arms 5, 6 is displaced, then the bolt 7 and the nut 8 are again fastened, thus the ball center distance (d) can be easily adjusted. |
