| description | PROBLEM TO BE SOLVED: To provide a sealing device and a sealing structure which can reduce the wear of a slide face while securing high seal performance, in the sealing device and the sealing structure for sealing an annular clearance between a shaft which relatively and reciprocally moves and a housing.SOLUTION: A rubber elastic-body made sealing device 100 which seals an annular clearance between a shaft 200 and a housing 300 which relatively reciprocate, and seals a working fluid into a region at a sealing side O comprises an internal peripheral lip part 110 which is attached to an annular groove 310 formed at the housing 300. A plurality of annular notches 160 are formed in a region at an atmosphere side A with respect to an internal peripheral lip part 110 at an internal peripheral face 101 of the sealing device 100 being a region which slides with respect to an external peripheral face 201 of the shaft 200, and the notches 160 are inclined toward the atmosphere side A as progressing toward an external peripheral side from the internal peripheral face 201.SELECTED DRAWING: Figure 1
【課題】相対的に往復運動する軸とハウジングとの間の環状隙間を密封する密封装置及び密封構造において、高いシール性を確保しつつ、摺動面の摩耗を低減させることのできる密封装置及び密封構造を提供する。【解決手段】相対的に往復運動する軸２００とハウジング３００との間の環状隙間を密封して、密封側Ｏの領域内の作動油を密封するゴム状弾性体製の密封装置１００は、ハウジング３００に形成された環状溝３１０に装着されるものであって、内周リップ部１１０を備え、密封装置１００の内周面１０１における、内周リップ部１１０よりも大気側Ａの領域であって、軸２００の外周面２０１に対して摺動する領域には、環状の切り込み１６０が複数形成されており、切り込み１６０は、内周面２０１から外周側に進むにつれて大気側Ａに向かって傾いている。【選択図】図１ |
