Abstract

　サイドリップを有する密封装置を複数積み重ねたときにサイドリップが干渉するのを有効に抑えることができる密封装置を提供する。この目的達成のため、相対回転する二部材のうちの一方に装着されて他方に摺動自在に密接する密封装置であって、一方の部材に嵌合される取付環と、取付環に被着されたゴム状弾性体との組み合わせよりなり、ゴム状弾性体によって他方の部材に摺動自在に密接するサイドリップが成形されている密封装置において、取付環は、一方の部材の周面に嵌合される位置に円筒部を有し、ゴム状弾性体は、円筒部の軸方向一方に配置されたゴム段部を有する。円筒部およびゴム段部は、複数の密封装置を積み重ねたときに一の密封装置におけるゴム段部の上にその上方の密封装置における円筒部が載せられる位置関係を有し、かつこのとき一の密封装置におけるサイドリップは上方の密封装置に干渉しない寸法関係を有する。
