    摘要： Provided is a bearing device for a wheel that can realize prevention of a backlash in a circumferential direction and is excellent in workability of connection of a hub wheel and an outer joint member of a constant velocity universal joint. Further, provided is a bearing device for a wheel that can prevent deterioration in NVH characteristics, which is caused by the backlash occurring in a joint section between the hub wheel and the constant velocity universal joint or between an outer member and a knuckle, and can perform rotation torque transmission with high accuracy. The bearing device includes a recess-projection fitting structure (M) in which the hub wheel (1) and a shaft section (12), which is fitted in a hole (22) of the hub wheel (1) of the outer joint member of the constant velocity universal joint (3) are unitized together. In the recess-projection fitting structure (M), entire fitting regions among projections (35) on the outer surface of the shaft section (12) of the outer joint member and recesses (36), which fit on the projections, are brought into intimate contact with each other.

    摘要： Provided is a small-sized, lightweight, low-cost, and highly reliable bearing device for a driving wheel which needs no tapered spline, and eliminates a circumferential backlash in spline fitting portions to thereby prevent unusual noise. The bearing device for a driving wheel comprises an outer race (5) having an inner periphery in which double-row outer raceway surfaces (13, 14) are formed; a hub wheel (1) and an inner race (2) having outer peripheries in which double-row inner raceway surfaces (7, 8) opposed to the outer raceway surfaces (13, 14) are formed; and double-row rolling elements (3, 4) interposed between the outer raceway surfaces (13, 14) of the outer race (5) and the inner raceway surfaces (7, 8) of the hub wheel (1) and the inner race (2). A shaft hole (28) of the hub wheel (1) is formed into a cylindrical shape, and a male spline (26) is formed on an outer periphery of a stem section (27) of the outer joint member (15) so that the stem section (27) of the outer joint member (15) is press-fit into the shaft hole (28) of the hub wheel (1). With this, recesses caused to closely fit on the male spline (26) with interference are formed in the shaft hole (28) of the hub wheel (1), whereby the hub wheel (1) and the outer joint member (15) are separably coupled to each other.

    摘要： The present invention firmly connects an inner joint component and a shaft of a constant velocity universal joint, making it difficult for backlash to occur. An axis hole inner diameter 26 of an inner member 20 of the constant velocity universal joint is unhardened, and a spline 54 serving as a recess and projection section running along a circumferential direction is formed on an axial end outer diameter 52 of the shaft 50. A hardened layer n is formed on the axial end outer diameter 52 of the shaft 50. The shaft 50 and the inner member 20 are joined by an axial end of the shaft 50 being pressed into the axis hole inner diameter of the inner member 20 to incuse a shape of said recess and projection section onto the axis hole inner diameter 26 of the inner member 20.
