ことを特徴とするテンシヨナ装置。 a body; a plunger that is slidably inserted into the body and presses the tensioner band against the chain; a first spring that is interposed between the body and the plunger and biases the plunger in the forward direction; a first formed between the plungers;
In the tensioner device provided with a hydraulic chamber, a piston is slidably inserted into the body, a second spring for biasing is provided between the body and the piston, and a second hydraulic pressure is provided between the body and the piston. A check valve is disposed in the piston to prevent the flow of oil from the first hydraulic chamber to the second hydraulic chamber, and when the hydraulic pressure in the first hydraulic chamber increases due to the movement of the plunger, the piston 1. A tensioner device comprising a biasing means for retracting the pressure and maintaining a constant pressure in the first hydraulic chamber.
