    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 method of manufacturing a spline telescopic shaft includes a masking step in which, in a prescribed axial-direction region (L1; L2) of an intermediate manufacturing product, partial tooth grooves (G) that are equally spaced circumferentially are respectively covered by masking members (70; 70P; 70Q; 70R; 70S) that are equally spaced circumferentially; a resin coating step in which a resin layer (43A; 53PA) is formed, and inner surfaces of the partial tooth grooves (G) covered by the masking members (70; 70P; 70Q; 70R; 70S) are left as metal exposed portions (44; 54P) that are equally spaced circumferentially; and a coating film forming step in which, in a state where the intermediate manufacturing product provided with the resin layer (43A; 53PA) is centered with respect to a broach (80; 80P) via the metal exposed portions (44; 54P), the intermediate manufacturing product and the broach (80; 80P) are caused to slide relative to each other in an axial direction by press-fitting such that the resin layer (43A; 53PA) is shaved to form a resin coating film (43; 53P).

    摘要： A shaft (3) has a central axis (L3) and includes first and second members (11, 12) that are identical in shape and that form a shaft portion for providing one end of the shaft (3) in an axial direction that the central axis extends in. Each of the first and second members (11, 12) includes a plate (111, 121) and an arm portion (112, 122). The plates (111, 121) extend in the axial direction. The arm portions (112, 122) are located closer to the end of the shaft (3) than the plates (111, 121) and are located farther from the central axis (L3) than the plates (111, 121). The plates (111, 121) face each other across the central axis (L3). The arm portions (112, 122) are couplable with a joint spider.

    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.

    摘要： A first yoke includes a tubular portion extending in a first direction, a flange, and a pair of arms extending from the flange. Support holes for a joint spider are formed at tips of the respective arms. The arms have respective inner surfaces facing each other in a second direction. Each of the inner surfaces includes a first recessed portion and a second recessed portion as viewed in a third direction orthogonal to the first direction and the second direction. The first recessed portions are recessed such that the distance between the inner surfaces of the arms increases from a start end located closer to an opening edge of each support hole toward an end point located closer to a base end of the arm. Each of the second recessed portions connects the end point to an end surface of a flange so as to form a curved surface.
