Zusammenfassung:	To provide interchangeability with a roller chain of a standard specification without a seal even though a seal ring is provided to a bearing part between a bushing and a roller.SOLUTION: A recessed part 15 is so formed on both end surfaces of a roller 6 as to surround a bushing 5, and a bottom surface 15a of the recessed part receives a seal plate 16, and a seal ring 12 is housed thereon. The seal ring 12 protrudes by a predetermined amount from the recessed part 15, and is brought into contact with an inside surface 4d of an inner plate 4 composed of a flat surface, by a predetermined crushing margin.SELECTED DRAWING: Figure 2 【課題】ブシュとローラとの間の軸受部にシールリングを設けたものでありながら、シールを有さない標準仕様のローラチェーンとの互換性を可能とする。【解決手段】ローラ６の両端面にブシュ５を囲むように凹部１５を形成し、該凹部の底面１５ａをシールプレート１６を受入れ、その上にシールリング１２を収納する。シールリング１２は、該凹部１５から所定量突出して平坦面からなる内プレート４の内側面４ｄに所定の潰し代で接触する。【選択図】図２
