To provide a wheel bearing device capable of suppressing the entry of foreign matters such as muddy water spreading from a flange part into a bearing space without the need to enlarge the bearing space.SOLUTION: The wheel bearing device includes an outward member 2, an inward member 1 having a flange part 6, double row rolling elements rollingly stored between both the rolling surfaces of the inward member 1 and the outward member 2 via a cage, and a seal device 10 mounted to the end of the annular space of a bearing. An external seal 30 for covering a clearance in the axial direction formed between an outer side end 22 of the outward member 2 and a flange part 6 side of a hub ring 4 is mounted to the flange part 6, The external seal 30 has a base part 30p mounted to the flange part 6, and an eaves part 30a extending from the base part 30p to the inner side while inclining in the inner diameter direction.SELECTED DRAWING: Figure 5

    【課題】 軸受空間を大きくすることなく、フランジ部を伝ってくる泥水等の異物の軸受空間への侵入を抑制することができる車輪用軸受装置を提供する。【解決手段】 外方部材2と、フランジ部6を有する内方部材1と、この内方部材1と外方部材2の両転走面間に保持器を介して転動自在に収容された複列の転動体と、軸受の環状空間の端部に装着されたシール装置10とを備えた車両軸受装置であって、外方部材2のアウタ側端部22とハブ輪4のフランジ部6側との間に形成される軸方向の隙間を覆う外部シール30がフランジ部6に取り付けられ、外部シール30は、フランジ部6に取り付けられるベース部30pと、ベース部30pからインナ側に内径方向に傾斜して延びる庇部30aと、を有する。【選択図】 図5
