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).

Abstract: Provided are: a sensor holder that can prevent influence on the performance of encoder reading by a sensor; and the like. A sensor holder 12 is provided with: a cap part 121 that is fitted into an outer ring 2 so as to cover an inner-side opening 2a of the outer ring 2; a sensor support part 122 that, at a portion of the cap part 121 opposing a magnetic encoder 11, protrudes from the cap part 121 toward one side in the axial direction, and supports a rotation speed sensor 13 for detecting displacement of the magnetic encoder 11; and a nut holding part 123 that protrudes from the cap part 121 toward the one side in the axial direction and holds a nut 124 for securing the rotation speed sensor 13 onto the cap part 121. The sensor support part 122 and the nut holding part 123 are formed separately, and one axial end surface 124a of the nut 124 held by the nut holding part 123 protrudes further toward the one side in the axial direction than one axial end surface 122c of the sensor support part 122.
