Embodiment Construction
[0074] Below, based on figure 1 ˜ FIG. 9 describe an embodiment of the present invention. figure 1 1 shows a bearing device for a wheel according to the first embodiment. This bearing device for a wheel integrates a hub wheel 1, a multi-row rolling bearing 2, and a constant velocity universal joint 3, and the hub wheel 1 is inserted into the hole of the hub wheel 1. The shaft portion 12 of the outer joint member of the constant velocity universal joint 3 in the portion 22 is detachably coupled via the concave-convex fitting structure M. As shown in FIG.
[0075] Such as Image 6 As shown, the constant velocity universal joint 3 is composed of the following main components: an outer ring 5 as an outer joint member; an inner ring 6 as an inner joint member arranged inside the outer ring 5; A plurality of balls 7 that transmit torque between them; a cage 8 that is interposed between the outer ring 5 and the inner ring 6 and holds the balls 7 . The inner ring 6 is torque-tran...
