<P>PROBLEM TO BE SOLVED: To provide a bearing device for a wheel capable of reducing its weight, miniaturizing it, setting and providing a predetermined negative clearance in a bearing easily and accurately, and improving reliability. <P>SOLUTION: In this bearing device for the wheel integrating inward members 5 by plastic connection, an outward member 4 is composed of a first outward member 21 and a second outward member 22 fitted internally into an annular recessed part 21b formed at its inner periphery and arranged so as to move in the axial direction, a collar part 24 extending outward in the radial direction is protrudedly provided in an end part of the second outward member 22, the second outward member 22 is separated from the first outward member 21, and a spacer 25 having predetermined width is provided in a clearance formed between an end face of the first outward member 21 and the collar part 24 of the second outward member 22. Consequently, even if the bearing has a pre-load structure, the negative clearance can be easily and accurately set and provided to improve reliability. <P>COPYRIGHT: (C)2006,JPO&NCIPI |
