  • Patent number: 10837527
    Abstract: To provide a tensioner capable of keeping, with a simple structure, oil pressure in an oil pressure chamber stable. The tensioner includes a pressure adjusting mechanism that adjusts oil pressure in the oil pressure chamber. The pressure adjusting mechanism includes a cylinder part, a piston unit set inside the cylinder part so as to be able to approach and separate from the oil pressure chamber, and piston biasing units that bias the piston unit toward the oil pressure chamber. A liquid tight seal condition is kept between the cylinder part and the piston unit at any position between a position where the piston unit has moved closest to the oil pressure chamber and a position where the piston unit has moved closest to the adjustment space. The piston biasing units include at least two piston springs.
