摘要： In a steering system, a first universal joint 9 includes a first yoke 20 coupled to an intermediate shaft 4. A second universal joint 10 includes a fourth yoke 60 paired with a third yoke 50 coupled to the intermediate shaft 4 and a shaft attachment portion 70 joined to the fourth yoke 60 and in which a bolt insertion hole 73 allowing a pinion shaft 5 to be clamped is formed. When an angle β between the intermediate shaft 4 and a steering shaft 3 is set to θ1, an around-axis angle α of the first yoke 20 in a rotating direction S is set to ω1, and an angle between the intermediate shaft 4 and the pinion shaft 5 is set to θ2, a junction angle ε between the fourth yoke 60 and the shaft attachment portion 70 in the rotating direction S is adjusted to set an around-axis angle φ of the bolt insertion hole 73 in the rotating direction S to a preset angle ω2.

摘要： A bearing of a universal joint includes a cylindrical bearing cup fitted into a bearing hole, and a plurality of rolling elements aligned between the bearing cup and a shaft part. In a simulation step of the method for manufacturing the universal joint, a simulation is enacted of a compressed state when a sample bearing cup selected from the same lot is fitted into a reference hole of a reference jig and only the outside diameter is restricted. In a measurement step, the inscribed circle diameters are measured for a plurality of rolling elements held in the sample bearing cup in the simulated compressed state. In an outside diameter setting step, the outside diameter of the shaft part is set to an outside diameter of the shaft part needed for necessary radial gaps to be attained in accordance with the inscribed circle diameters. In a bearing cup insertion step, the sample bearing cup or a bearing cup in the same lot that has not undergone the measurement step is inserted along with the plurality of rolling elements between the shaft part and the bearing hole.
