Abstract

　製造コストの低いチェーンテンショナを提供する。 　シリンダ１１内にプランジャ１４を摺動可能に挿入してシリンダ１１内に圧力室１５を形成し、給油通路１６をシリンダ１１に設け、その給油通路１６の圧力室１５側の端部にチェックバルブ１７を設け、プランジャ１４とシリンダ１１の摺動面間にリーク隙間１８を形成し、圧力室１５内に組み込んだリターンスプリング２８でプランジャ１４をシリンダ１１から突出する方向に付勢し、そのプランジャ１４でチェーン６を押圧するようにしたチェーンテンショナ１において、プランジャ１４のシリンダ１１からの突出端面から圧力室１５に至る貫通孔３１をプランジャ１４に設け、その貫通孔３１に、外周に雄ねじ３３を有するプラグ３２を圧入して貫通孔３１の内周とプラグ３２の外周との間に螺旋状のエア抜き通路３４を形成する。
