摘要： The present invention relates to a bearing apparatus for a wheel of vehicle comprising: an outer member (10) formed on its inner circumferential surface with double row outer raceway surfaces (10a, 10a); an inner member (1) including a hub wheel (2) having a wheel mounting flange (4) formed integrally therewith at one end thereof and a cylindrical portion (2b) axially extending from the wheel mounting flange (4), and an inner ring (3) press fitted on the cylindrical portion (2b) formed on its outer circumferential surface with one of double row inner raceway surfaces (2a, 3a) arranged oppositely to one of the double row outer raceway surfaces (10a, 10a); double row rolling elements (6, 6) contained and held by cages (7, 7) freely rollably between the double row outer raceway surfaces (10a, 10a) of the outer member (10) and the double row inner raceway surfaces (2a, 3a) of the inner member (1); and wherein an end face at the outboard side of the inner ring (3) is adapted to be abutted to a stepped portion (11) formed on the hub wheel (2) and the inner ring (3) is secured on the hub wheel (2) with being sandwiched between a caulked portion (2c) formed by plastically deforming radially outward an end at the inboard side of the cylindrical portion (2b) of the hub wheel (2) and the stepped portion (11) of the hub wheel (2) characterized in that : a ratio ( ) of the thickness (e) of an end (3c) at the outboard side of the inner ring (3) to be abutted to the stepped portion (11) relative to the inner diameter (d) of the inner ring (3) is limited at or smaller than a predetermined value.

摘要： PROBLEM TO BE SOLVED: To provide a bearing device for a wheel for preventing an inner ring from coming off in an assembling process for a vehicle, and reducing the amount of shift of the inner-ring in the assembling process. SOLUTION: An inside member 2 includes a hub ring 9 provided with a hub flange for fitting a wheel on the outside periphery and a through hole 11 in the center, and the inner ring 10 fit on the outside periphery of the inboard end of the hub ring 9. Raceway surfaces 4 are formed respectively in the hub ring 9 and the inner ring 10. On the surface of the inside periphery of the inner ring 10, a step 16 is formed which is continued to an inboard end face 10a of the inner ring 10, and has a depth corresponding to the edge of the inside periphery of the end face 10a. A plastically deformed part 9b in caulking the hub ring 9 is fit to the step 16 of the inner ring 10. The plastically deformed part 9b is not protruded from the end face 10a of the inner ring 10. A hub-ring fitting face 10b of the inside-diameter face continued to the step 16 of the inner ring 10 is finished as a ground surface. The joint 16ba between the hub-ring-fitting face 10b and the end face 16b in the step 16 has a pointed form. COPYRIGHT: (C)2007,JPO&INPIT
