する密封式オートテンシヨナ。 A rod insertion hole is formed in the rod cover provided at the end of the cylindrical body, and a retractable boot is placed on the outside of the part of the rod that is slidably inserted into the rod insertion hole, and is located inside the body. One end is fixed to the inner circumferential surface of the body, the other end is fixed to the rear end of the rod via a rod cap, and a plunger is slidably incorporated inside the body, and a sealed supply chamber is formed at the front and rear of the plunger. A pressure chamber is provided, a fluid is sealed in both chambers, a communication path is formed between both chambers, and a pressure regulating spring is provided in the pressure chamber at the rear of the plunger to press the plunger against the rear end of the rod. A sealed autotensioner characterized in that a rod fitted with the rod cap is loosely fitted into a recess formed at one end of the plunger, and a groove passing through the center of the rod cap is formed in the end face of the rod cap.
