<P>PROBLEM TO BE SOLVED: To provide a bearing device for a driving wheel with restrained NVH capable of separating a bearing part from a universal joint in an axial direction with a simple structure without strictly managing a dimension of a connection part. <P>SOLUTION: This device comprises an outward member 4 with plural rows of outside rolling faces 4a formed on an inner periphery, and an inward member 5, on which a wheel mounting flange 8 and an inside rolling face 1a are formed, and which is equipped with a hub wheel 1 with hardened indentations and projections 14 formed on an inner periphery, and an inner wheel member 7 which is internally fitted with the hub wheel 1 to plastically couple with a fit part 9b, and at the end of which a connection part 10 extends. A connection part 21 engaged with the connection part 10 is formed on an outside joint member 15, and serrations 21a, 10a are formed on inner and outer peripheries thereof. A shrinkable bellows-like connection member 22 is interposed between the opposed serrations in an axial direction, and the universal joint 3 and a bearing part are integrated separatably in the axial direction by a fixing bolt 25 fastened to the outside joint member 15. <P>COPYRIGHT: (C)2007,JPO&INPIT |
