Abstract
The problem to be solved is to provide a tensioner lever that inhibits friction-induced wear or seizure on a surface of a pivoting support boss contacting a shoulder bolt so that high durability is achieved, and that is easily producible and enables cost reduction. As a solution to the problem noted above, the tensioner lever includes a shoe having a traveling surface, a lever body, and a pivotal support boss provided at a proximal end of the lever body to allow a distal end thereof to swing. The shoe and the lever body are integrally formed and assembled together by double injection molding. The lever body includes a slide bearing member, and a connecting part that connects the slide bearing member and the shoe. The slide bearing member, the connecting part, and the shoe are made of the same synthetic resin, and configured as a continuous one-piece component.
