Claims (2)
- 車両用ベアリング装置に装着される密封装置であって、前記ベアリング装置の内部に向けて設けられ、相手摺動部材に全周に亙って摺動可能に接触するリップ摺動部により前記ベアリング装置内部の潤滑用グリースが前記ベアリング装置外部へ漏洩するのを抑制するシールリップを有する密封装置において、
前記リップ摺動部の範囲内であって前記リップ摺動部の円周上一部に設けられ、前記相手摺動部材に当接することにより、前記ベアリング装置の組立て時に上昇する前記ベアリング装置の内部圧力を開放する開放流路として利用される間隙を周辺に形成する突起を備え、
前記突起は、
そのベアリング内部側の端部が前記シールリップの先端部に位置して設けられ、
所定の稼働時間経過後に摩滅して前記間隙を消失させる、
ことを特徴とする密封装置。 - 請求項1記載の密封装置において、
前記突起は、軸方向に延びるリブ状の突起として設けられていることを特徴とする密封装置。
