Document Type and Number:
WIPO Patent Application WO/2020/036093
Kind Code:
A1
Abstract:
The present invention addresses the problem of providing a bearing device for wheels, which is configured so that, at the time of fitting of a fitting cylinder section of an outer member into a fitting hole section in a vehicle body-side member, the fitting section of a cap member does not interfere with an inner peripheral edge of the fitting hole section. In a bearing device (1) for wheels, in which a fitting cylinder section (2h) formed at the inner end section of an outer member (2) is affixed while being fitted in a fitting hole section (9h) in a vehicle body-side member (9), a large-diameter section (2i) is formed on the outer side of the fitting cylinder section (2h), and a small-diameter section (2j) is formed on the 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 the 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).
