徴とするオートテンシヨナ。[Claim for Utility Model Registration] A piston rod is fixed to a piston loosely fitted in a cylinder filled with oil, and a spring applies a protruding force to the rod, thereby communicating the piston front chamber and the piston rear chamber in the cylinder. A check valve that allows oil to flow into the piston rear chamber is provided in the oil passage, and an oil reservoir with a diaphragm is provided in communication with the piston front chamber to absorb the oil volume fluctuation and keep the amount of oil filled in the piston constant. In the autotensioner that applies tension to the timing belt by the ejecting force, a diaphragm inversion prevention plate is installed adjacent to the diaphragm position before deformation to resist diaphragm deformation due to an increase in oil volume and prevent its inversion. An autotensioner characterized in that the plate is provided outside the reservoir and is movable in the direction of deformation of the diaphragm.
