摘要：PURPOSE:To achieve smooth rotation by forming at least one of a ball and a ball groove with reinforced plastic having lower resiliency and producing pressure contacting force through resilient deformation at the contacting section between the ball and the ball groove. CONSTITUTION:The yoke joint in equi-speed joint is formed by burrying a steel material as a core metal 3 into the reinforced plastic material. The ball groove 2 for containing the ball 1 is finished with minus tolerance against the curvature of ball 1 when molding. Consequently, when assembling, the ball 1 is inserted into the ball groove 2 then they are pressure contacted continuously through resilient deformation of the plastic material. As a result, the ball 1 can be contained tightly in the ball groove 2 to simplify adjusting of pre- pressurization thus to enable smooth transmission of rotation from input side yoke to the output side yoke even for high joint angle.
