Claims

[Claims for Utility Model Registration] (1) An outer ring having a plurality of convex portions on its inner peripheral surface having cylindrical surfaces in the axial direction on both side walls, and an outer ring having cylindrical surfaces in the axial direction on both side walls, an inner ring having a protrusion located between the protrusions on its outer peripheral surface; a ball interposed between the cylindrical surfaces of the protrusions of the inner and outer rings to transmit torque;
a retainer for holding the balls, the contact points between each of the inner circumferential surfaces and the balls are located on the pitch circumference of the balls, and the line of action of the rotational torque at each contact point and the A constant velocity universal joint in which the tangent line of the ball is perpendicular. (2) Each ball has a ball accommodating part on both sides that restricts the axial movement of each ball, and the outer surface is guided in contact with the inner circumferential surface of the outer ring, and the inner surface is guided in contact with the outer surface of the convex part of the inner ring. 2. The constant velocity universal joint according to claim 1, further comprising a retainer comprising a plurality of ball holding sections, and an arm section that integrally connects the plurality of ball holding sections.
