Abstract

Official abstract text for this publication.

A bearing device for a vehicle wheel includes an outer member which is a plastic work piece in which an open hole in an outer-side end part is pushed out from inner sides, and an outer periphery of the outer member has a bulged part that is enlarged radially outward.

First claim

Opening claim text (preview).

The invention claimed is: 1. A method for manufacturing a bearing device for a vehicle wheel, the bearing device including: an outer member having, on an inner circumference thereof, double-row outer raceway surfaces integrally formed on the outer member, the outer member further having a knuckle-mounting flange; an inner member including: a wheel hub having a vehicle wheel-mounting flange integrally formed thereon, and having, on an outer circumference thereof, a cylindrical portion extending axially and at least one inner ring press-fit on the cylindrical portion of the wheel hub; the inner member having, on an outer circumference thereof, double-row inner raceway surfaces facing the double-row outer raceway surfaces; and double-row rolling elements rollably disposed between the double-row outer raceway surfaces of the outer member and the double-row inner raceway surfaces of the inner member, respectively, the method comprising: widening an opening by pressing in an outer-side end of the outer member from an inside of the outer member by a forging method to form a bulged portion on an entire outer circumference of the outer member, wherein the bulged portion bulges radially outward, and wherein the outer member is pressed between a first die located axially opposite the outer-side end and a second die located axially on the outer-side end to form the bulged portion whereby the first die presses a first side of the knuckle-mounting flange extending in a radial direction and a second side of the knuckle-mounting flange extending in the radial direction axially opposite to the first side of the knuckle-mounting flange is not contacted during pressing.
