To provide a sealing device which can be improved in muddy water resistance.SOLUTION: A sealing device 15 comprises: a slinger 30 having a first cylinder part 31 fit to an external peripheral face of a hub shaft 11, and fixed to the hub shaft 11, a circular plate part 32 extending to the outside in a radial direction along a side face of a flange part 56 from an end part of the first cylinder part 31 at a vehicle outer-side, and a second cylinder part 33 extending to a vehicle inner-side from an external peripheral end part of the circular plate part 32; a core grid 25 fit to an end part of an outer ring 12 at the vehicle outer-side, and fixed to the outer ring 12; a seal lip 21 fixed to the core grid 25, and coming in slide-contact with the first cylinder part 31 and the circular plate part 32; and a cylindrical deflector 23 which is fixed to the core grid 25 and in which an external peripheral face is arranged opposite to an internal peripheral face of the second cylinder part 33, which therefore forms a labyrinth clearance S between the second cylinder part 33 and the deflector 23. An end face 33a of the second cylinder part 33 at the vehicle inner side is arranged on a plane flushed with an end face 23a of the deflector 23 at the vehicle inner side.SELECTED DRAWING: Figure 2

    【課題】耐泥水性を向上させることができる密封装置を提供する。【解決手段】密封装置15は、ハブ軸11の外周面に嵌合してハブ軸11に固定される第1円筒部31、第1円筒部31の車両アウタ側の端部からフランジ部56の側面に沿って径方向外方に延びる円板部32、及び円板部32の外周端部から車両インナ側に延びる第2円筒部33を有するスリンガ30と、外輪12の車両アウタ側の端部に嵌合して外輪12に固定される芯金25と、芯金25に固定され、第1円筒部31及び円板部32に摺接するシールリップ21と、芯金25に固定され、外周面が第2円筒部33の内周面に対向して配置されることで第2円筒部33との間でラビリンス隙間Sを形成する円筒状のデフレクタ23とを備える。第2円筒部33の車両インナ側の端面33aが、デフレクタ23の車両インナ側の端面23aと同一面上に配置されている。【選択図】図2
