【実用新案登録請求の範囲】[Scope of utility model registration request] 相対運動自在に配置された二つの部材のうちの
一方の部材に密封接触する環状のシールリツプと
、他方の部材の外部端面の内部側に軸方向の環状
段差部を介して設けた内部端面に密着する環状の
本体部とを備え、本体部の外周に、環状段差部に
所定の締め代で密封接触する環状の突起を設ける
とともに、本体部の軸方向の厚さを、他方の部材

定したことを特徴とする密封装置。 An annular sealing lip that sealsly contacts one of the two members arranged to allow relative movement, and tightly contacts the inner end surface provided on the inner side of the outer end surface of the other member via an axial annular step. An annular protrusion is provided on the outer periphery of the main body to make sealing contact with the annular stepped portion with a predetermined interference, and the axial thickness of the main body is determined by the inner end surface of the other member. 1. A sealing device characterized in that the size is set such that the non-adhesive side end surface of the main body part is flush with the external end surface of the other member when the main body part is in close contact with the other member.
