Abstract
A tensioner lever for chain drives has an internal space formed therein for accommodating within it at least a coiled portion of a torsion coil spring. The internal space has an opening for enabling the torsion coil spring to be assembled in the internal space. The lever body further has a boss disposed inside the internal space. The boss has an axial hole through which a pivot shaft extends and an outer peripheral surface around which the coiled portion of the torsion coil spring is loosely fitted, the axial hole and the outer peripheral surface being concentric with each other. The tensioner lever of the foregoing construction requires only a small space for installation to a mount surface and can be easily and speedily assembled onto the mount surface.
