Abstract
Provided is a bearing device for a vehicle wheel that is suitable in being able to prevent impairment in assemblability of the bearing device for a vehicle wheel to a knuckle without cost increase. A bearing device for a vehicle wheel (1) is provided with an inner member and an outer ring (2) which is an outer member having a vehicle-body-mounting flange part (2d), wherein the outer ring (2) has a pilot part (2e) disposed inward of the vehicle-body-mounting flange part (2d), and the pilot part (2e) has a fitting portion (2f) configured to be fitted to a knuckle (10) and a guiding portion (2g) having a diameter which gradually decreases inward from the inner-side end of the fitting portion (2f).
Claims5
A bearing device for a vehicle wheel, comprising:
- an outer member having a plurality of rows of outer raceway surfaces on an inner periphery and a flange portion to which a vehicle body side member is attached;
- an inner member including a hub ring including a small diameter step portion extending in an axial direction on an outer periphery and at least one inner ring press-fitted into the small diameter step portion of the hub ring, the inner member having a plurality of rows of inner raceway surfaces facing the plurality of rows of outer raceway surfaces on an outer periphery;
- and
- a plurality of rows of rolling bodies rollably accommodated between the raceway surfaces of the inner member and the raceway surfaces of the outer member, wherein
- the outer member is provided with a pilot portion on a more inner side than the flange portion, and
- the pilot portion has a fitting portion fitted to the vehicle body side member and a guide portion whose diameter gradually decreases from an inner-side end portion of the fitting portion toward an inner side.
