Abstract

　カムの回転によりアジャストスクリュに押し込み方向の荷重が負荷されたときに、アジャストスクリュが回転して押し込み方向に移動するのを防止する。 　シリンダヘッド２の上面に開口した収容穴１１に挿入される筒状のハウジング１２と、そのハウジング１２の内周に形成された雌ねじ１３にねじ係合する雄ねじ１４を外周に有するアジャストスクリュ１５と、そのアジャストスクリュ１５をハウジング１２から上方に突出する方向に付勢するリターンスプリング１７とを有し、アジャストスクリュ１５のハウジング１２からの突出端１９でアーム７を支持するラッシュアジャスタ１において、アジャストスクリュ１５の突出端１９の表面を、有機モリブデン入りオイルのオイル添加剤と非反応の材料で形成する。
