PROBLEM TO BE SOLVED: To easily improve a blade tensioner system in spring characteristic. SOLUTION: A blade tensioner 10 is formed which consists of a blade shoe 11 and a blade spring 12 disposed on the side opposite from the chain sliding surface 11a of the blade shoe for exerting pressure on a timing chain 4 via the blade shoe 11. The blade shoe 11 is rotatably supported by a shoulder bolt 14 passed through the rear end 13 of the blade shoe 11. In a set condition in which the blade tensioner 10 is incorporated into an engine, and in a condition in which the tension of the chain is increased from the set condition, the forward end 15 of the blade shoe 11 is slidably supported against first and second supporting faces 16 and 17 inside the engine.
