Embodiment Construction
[0099] Below, refer to figure 1 ~ Figure 21 illustrates an embodiment of the present invention. figure 1 A bearing device for a wheel according to the first embodiment is shown, and the bearing device for a wheel is formed by integrally integrating a hub 1 , a multi-row rolling bearing 2 and a constant velocity universal joint 3 .
[0100] The constant velocity universal joint 3 includes an outer ring 5 as an outer joint member, an inner ring 6 as an inner joint member disposed inside the outer ring 5 , and a plurality of joints sandwiched between the outer ring 5 and the inner ring 6 to transmit torque. The balls 7 and the cage 8 holding the balls 7 sandwiched between the outer ring 5 and the inner ring 6 are composed as main components. The inner ring 6 is spline-fitted by press-fitting the end portion 10 a of the shaft 10 into the inner diameter 6 a of the shaft hole, and coupled to the shaft 10 so that torque can be transmitted. In addition, a stop ring 9 for preventin...
