、請求項１のダイヤフラム密封式テンシヨナ。[Claims for Utility Model Registration] (1) A piston rod is fixed to a piston that is loosely fitted into an oil-filled cylinder with a small gap and divides the cylinder into a front chamber and a rear chamber, and is protruded from the rod by a spring. When a force is applied, a check valve is provided in an oil passage communicating between the front piston chamber and the piston rear chamber to allow oil to flow into the piston rear chamber, and the piston front chamber is connected to the cylinder and the piston rod at respective ends. In the diaphragm-sealed tensioner, which is sealed by a diaphragm with a fixed part and applies tension to the belt by the ejecting force, the piston rod is provided with a notched flat part, and the outer ring member press-fitted into the cylinder has a cross-sectional shape of the rod. A sealed diaphragm tensioner characterized by a fixed resin member with holes that fit the diaphragm. (2) The diaphragm sealed tensioner according to claim 1, wherein a sealing lip is formed in the hole.
