Abstract:
1. A method of manufacturing a wheel bearing device, the device comprising: an outer member having outer raceways in double rows at its inside periphery; an inner member having inner raceways in double rows facing to the outer raceways, an inside-diameter side member, and an outside-diameter side member fitted onto the inside-diameter side member with an irregular portion interposed in between; rolling members in double rows disposed between the outer raceways and the inner raceways, wherein when the inside-diameter side member and the outside-diameter side member are joined together by swaging through expansion of at least a part of the inside-diameter side member by a swaging jig pushed into an inside of the inside-diameter side member to make the irregular portion bite into an opposing face, the inside-diameter side member is expanded in diameter while being pressed by the swaging jig toward axially one side with the inside-diameter side member being made to axially butt against the other side of the outside-diameter side member and the outside-diameter side member at the axially one side being supported by a receive member, wherein a compression strain remains at and around portions of the inside-diameter side member butting against portions of the outside-diameter side member.
