Abstract
In a bearing device for a vehicle wheel (1), a large-diameter section (2i) is formed on an outer side of a fitting cylinder section (2h), and a small-diameter section (2j) is formed on an inner side of the fitting cylinder section (2h). A cap member (8) is formed by bending a metal steel plate, and has a cover plate section (81) which closes the inner open end of an outer member (2) and a fitting section (82) which is fitted over the small-diameter section (2j). A tapered portion (83) based on the spring back angle θ of the fitting section (82) is provided at the outer peripheral edge of the outer end section of the fitting section (82).
Claims4
A bearing device for a vehicle wheel, comprising:
- an outer member formed with an outer raceway surface;
- an inner member that includes a hub ring and at least one inner ring that is fitted over the hub ring, the inner member being formed with an inner raceway surface;
- a rolling member interposed between respective raceway surfaces of the outer member and the inner member;
- and
- a cap member that is fitted over the outer member,
- the bearing device for a vehicle wheel being fixed in a state where a fitting cylinder section formed at an inner end section of the outer member is fitted into a fitting hole section of a vehicle body-side member, wherein,
- wherein a large-diameter section is formed on an outer side of the fitting cylinder section,
- a small-diameter section is formed on an inner side of the fitting cylinder section, and
- the cap member is formed by bending a metal steel plate, to have a cover plate section that closes an inner open end of the outer member and have a fitting section that is fitted over the small-diameter section, the cap member being provided with a tapered portion based on a spring back angle of the fitting section, on an outer peripheral edge at an outer end section of the fitting section.
