<P>PROBLEM TO BE SOLVED: To provide a bearing device for a wheel for supporting a driving wheel capable of preventing an inner ring from coming off due to vibration in a period from shipment of a bearing to assembly on a vehicle while suppressing deformation of the inner ring and reduction of width of a flat face on an end face of the inner ring. <P>SOLUTION: This bearing device for the wheel is provided with an outward member 1 having rolling faces 3 in double rows at the inner periphery, an inward member 2 having rolling faces 4 opposing to each rolling face 3 at the outer periphery, and rolling bodies 5 in double rows between opposing rolling faces 3 and 4 to support the wheel which becomes the driving wheel for a vehicle body rotatably. The inward member 2 is composed of a hub wheel 9 having a flange 9a for attaching the wheel and the inner ring 10 fitted into the outer periphery at an in-board side end of the hub wheel 9. A recessed part 11 extending in the circumferential direction is provided on either of an inside diameter face of the hub wheel 9 and an outside diameter face of the hub wheel 9 fitted into the inside diameter face, and a projecting part 12 extending in the circumferential direction and engaged with the recessed part 11 is provided on the other side to prevent the inner ring 10 from coming off the hub wheel 9 by the engagement of the recessed part 11 and the projecting part 12. <P>COPYRIGHT: (C)2006,JPO&NCIPI |
