Abstract

　装着性及びシール性の向上を図ることができるシールリングを提供する。 　一箇所で分離されている有端状の形状を有し、嵌合可能に構成された両端部３、４を一時的に開いて軸に設けられた環状溝に装着され、軸と軸が挿入される軸孔を有するハウジングとの間の環状隙間を密封するシールリング１であって、両端部３、４のうち一方の端部３は、周方向に突出した凸部３１を有し、他方の端部４は、凸部３１と組み合わされる凹部４２を有し、凸部４１と凹部４２とを摺動させながら嵌合して、両端部３、４を閉じるように構成されたシールリングにおいて、凹部４２は、周方向に対して傾斜した傾斜側面４２ａを有し、凸部３１と凹部４２との摺動部において、凸部３１の先端の縁部の一部が凹部４２の傾斜側面４２ａ上を摺動するように構成され、摺動部の一部を線状の摺動部１３としたことを特徴とする。
