Abstract
スリンガ2の振り切り作用によってシールを行う密封装置において、密接摺動部S2へのダストや泥水等の介入による摩耗及びこれによるシール性の低下を防止するため、スラストリップ12及びその内周側のラジアルリップ13が設けられ静止側部材101に取り付けられる静止側密封要素1と、回転側部材102に嵌着されるスリーブ21及びその一端から延びるフランジ22からなるスリンガ2とを備え、スラストリップ12がフランジ22に摺動可能に密接され、ラジアルリップ13がスリーブ21の外周面に摺動可能に密接され、スリーブ21の外周面に、ラジアルリップ13との密接摺動部S2よりフランジ22側に位置して、円周方向へ連続した堰部23を設けたものである。堰部23は、突条231又は溝からなるものとすることができる。
