In a toothed belt tensioner that is provided with a check valve that allows oil to flow into the piston rear chamber and that applies tension to the toothed belt using the ejection force, an oil passage that can be opened and closed to communicate the piston front chamber and the rear chamber with the cylinder. Tensioner for toothed belts.
