Abstract
An object of the present invention is to provide a tensioner lever that can reliably prevent displacement or detachment of a torsion coil spring, prevent the torsion coil spring from interfering with an attachment surface, and allow smooth attachment of the tensioner lever to the attachment surface. The tensioner lever includes a lever body having a shoe surface, and a torsion coil spring pressing the shoe surface toward a chain. The lever body includes a base part and a cylindrical boss. The torsion coil spring includes a helical part loosely fitted on an outer circumferential surface of the boss, a pressing arm making contact with the lever body, and a support arm supported on the attachment surface. The outer circumferential surface of the boss includes a restricting protrusion formed at a position closer to the attachment surface than the helical part.
