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.
