PROBLEM TO BE SOLVED: To provide a bearing device for a wheel which is low in cost, and improved in muddy water performance without using a new component.SOLUTION: A bearing device for a wheel comprises: an outer ring 12; an inner shaft 82; a plurality of rolling bodies 86; and a sealing device 16 for sealing an annular space existing between the outer ring 12 and the inner shaft 82. A disc-plate shaped flange 83 is integrally formed at the inner shaft 82. The outer ring 12 comprises an end face 55 which is integrally formed at the outer ring 12, and opposes the flange 83 in an axial direction with an interval with the flange. The end face 55 is protruded toward the flange at a vertical upper end side rather than a vertical lower end side in a state of being mounted to a vehicle, and a clearance in the axial direction between an end face at the vertical upper end side and the flange is smaller than a clearance in the axial direction between an end face at the vertical lower end side and the flange.SELECTED DRAWING: Figure 3
【課題】新たな部品を使用することなく、低コストで泥水性能を向上した車輪用軸受装置を提供する。【解決手段】車輪用軸受装置は、外輪12と、内軸82と、複数の転動体86と、前記外輪12と前記内軸82との間に存在する環状空間を塞ぐ密封装置16とを備えている。内軸82には、円板状のフランジ83が一体に形成されている。外輪12は、当該外輪12と一体に形成されて、フランジ83とすきまをもって軸方向に対向する端面55を備えている。端面55は、車両に搭載した状態で鉛直方向上端側の方が鉛直方向下端側よりフランジに向けて突出しており、鉛直方向上端側における端面とフランジとの軸方向のすきまは、鉛直方向下端側における端面とフランジとの軸方向のすきまより小さい。【選択図】図3
