Abstract
PURPOSE: To form a highly precise oil groove etc. on the spherical surface pedestal of connecting member composing spherical surface joint, by forming the groove preliminary broadening the width excessively anticipating the transformation of the groove at before and after of plastic processing.
CONSTITUTION: Plural ball rolling grooves are formed on the spherical surface pedestal of setting part of axis formed in a constant curvature at the ball joint etc. The above groove 21 is formed broadening the width with excess length corresponding to the change amount of circumference length of the spherical surgace pedestal preliminary before carrying out plastic processing of the spherical surface pedestal. Moreover, the second groove 22 extending along the groove 21, is provided at the bottom of the groove 21 and plastic tranformation of the setting part 23 is concentrated on the second groove 22. Hereby, the plastic transformation of the groove 21 is made small and highly precise groove is able to obtain.
