- 転がり軸受の内輪の肩部に周段部を設け、外輪に固着したシール環体の内周部から上記周段部の側面に沿って径方向に延びる内周シールリップの一部を上記周段部の側面に接触させた転がり軸受の密封装置において、上記シール環体の内周シールリップを、上記周段部の側面方向に延びる複数の内側リップから形成するとともに、上記シール環体の内周部と内側リップ間及び各内側リップ間の各連結部を軸方向斜め外方に互いに平行に延びるように形成し、かつ、上記各内側リップのうち先端内側リップのみが常時上記周段部の側面に接触しながら各連結部が順次軸方向にたわむことができるとともに他の内側リップは先端内側リップの所定量の摩耗後に初めて上記周段部の側面に接触するように形成したことを特徴とする転がり軸受の密封装置。
- 上記各内側リップのうち、先端内側リップを除く他の内側リップは、当初は上記周段部の側面との間でラビリンス密封部を形成することを特徴とする請求項1に記載の転がり軸受の密封装置。
- 上記シール環体の内周部から上記周段部の側面とは反対方向に延びる外側リップを形成して、該外側リップは軸受に対する併設部材との間でラビリンス密封部を形成することを特徴とする請求項1または2に記載の転がり軸受の密封装置。
