摘要： The present invention provides a blade-type tensioner system for a chain that can easily improve spring properties. The blade-type tensioner includes a blade shoe and a blade spring positioned on the back side of chain sliding surface of the blade shoe so as to impart tension to a chain through the blade shoe. The blade shoe is pivotably supported around a shoulder bolt inserted into a proximal end portion of the blade shoe, and a distal end portion of the blade shoe is slidably supported on a supporting face provided in the engine. Th distal end portion of the blade shoe contacts a flat, first supporting face at a point. When tension in the chain is increased, the distal end portion contacts a concave, second supporting face at a point which is continuous with the first supporting face. The blade tensioner also includes a stop mechanism.
