Abstract
An object of the present invention is to provide a tensioner lever that allows for reduction of the number of components and the weight, while being able to prevent vibration and noise during the running of the chain. The tensioner lever according to the present invention is configured such that a lever body rotatably supported on an attachment surface is urged to rotate toward the chain by the resilient force of a coil spring. The coil spring includes a pressing arm extending from one end of a helical part and contacting the lever body, and a support arm extending from another end of the helical part and supported by the attachment surface. The lever body includes an engagement portion configured to allow the support arm of the coil spring to be hooked thereon by resilient deformation, and to removably engage therewith by rebound resilience of the coil spring.
