A tensioner for a toothed belt is provided with a check valve that allows oil to flow into the piston rear chamber in an oil passage communicating between the piston front chamber and the piston rear chamber, and applies tension to the toothed belt by the ejection force. A tensioner for a toothed belt, characterized in that the oil passage directly communicates with the piston front chamber without going through the piston rod.
