Abstract
【解決手段】取付環2に径方向外方へ向けてフランジ部2cを設けるとともにフランジ部2cにハウジング11の端面部11aに密接するゴム状弾性体よりなる端面シール部3fを被着して端面部11aを被覆する。
【選択図】図1
Description
図1は、本発明の第一実施例に係る密封装置1の要部断面を示している。この密封装置1は例えば自動車用車輪懸架装置におけるベアリング部にハブシール(ハブベアリング用シール)として用いられるものであって、以下のように構成されている。
尚、上記第一実施例では、上記したようにゴム状弾性体よりなる端面シール部3fに外周側サイドリップ3jが設けられているが、この外周側サイドリップ3jはこれに代えて、図2に示すように、ラビリンスシール4を設けても良い。このラビリンスシール4は、サイドリップ3cの外周に位置して回転軸12の端面部12aとの間に微小間隙(環状をなす軸方向微小間隙)5を形成してラビリンスシール作用をなすものであって、外周側サイドリップ3jと同様の作用効果を発揮することができる。
