Zusammenfassung:	To provide a sealing device which can send back lubrication oil that has passed through a main lip to the outer side of the main lip efficiently.SOLUTION: A sealing device includes: a slinger having a cylindrical sleeve and an annular flange expanding from the sleeve to the radial outer side; and a fixed seal member which is attached to the housing and contacts with the slinger. The fixed seal member has an annular main lip which slidably contacts with an atmosphere side surface of the flange of the slinger, seals lubrication oil in the housing, and is formed by an elastic material. An inclined part, which gets closer to the atmosphere side toward the radial inner side, is formed at the atmosphere side surface of the flange of the slinger. The inclined part has a spiral slope surface.SELECTED DRAWING: Figure 2 【課題】メインリップを通過した潤滑油をメインリップの外側に効率的に送り戻すことが可能な密封装置を提供する。【解決手段】密封装置は、円筒状のスリーブと、スリーブから径方向外側に広がる円環状のフランジを有するスリンガーと、ハウジングに取り付けられて、スリンガーに接触する固定シール部材とを有する。固定シール部材は、スリンガーのフランジの大気側の面に摺動可能に接触し、ハウジング内の潤滑油を封止する、弾性材料から形成された円環状のメインリップを有する。スリンガーのフランジの大気側の面には、径方向内側ほど大気側に位置する傾斜部が形成されており、傾斜部は、渦巻状のスロープ面を有する。【選択図】図２
