オートテンシヨナにおいて、前記ロツドの軸方向
の移動を案内する軸受部材をボデイの内部に組込
んだことを特徴とする密封式オートテンシヨナ。 A plunger is slidably assembled inside the body, and the tip of a rod that moves in the axial direction together with the plunger projects outward from the end of the body. The hydraulic oil sealed in both chambers flows through a communication path that communicates the two chambers, and flows between the two chambers. In a sealed autotensioner in which the fluctuating load applied to the rod is alleviated by the elasticity of a pressure regulating spring that provides protrusion in the direction, a bearing member that guides the axial movement of the rod is attached to the body. A sealed auto tensioner that is built into the interior.
