Abstract

　プランジャの加工が容易なチェーンテンショナを提供する。 　一端が開口した有底筒状のシリンダ９内にプランジャ１０を軸方向に摺動可能に挿入し、外周に雄ねじ１５を有するスクリュロッド１６をシリンダ９内に組み込み、そのスクリュロッド１６の雄ねじ１５にねじ係合する突起１７をプランジャ１０の内周に設け、雄ねじ１５は、プランジャ１０をシリンダ９内に押し込む方向の力が作用したときに圧力を受ける圧力側フランク１８のフランク角を、遊び側フランク１９のフランク角よりも大きい鋸歯状とし、プランジャ１０とスクリュロッド１６の間に組み込んだリターンスプリング２０でプランジャ１０をシリンダ９から突出する方向に付勢し、そのプランジャ１０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１０の内周の突起１７を設ける範囲を、プランジャ１０の内周のうちの円弧状の範囲とする。
