Abstract

A slide rail for tightening a chain has a pivot bearing at one end. A torsion spring is arranged coaxially thereto. The pivot bearing is designed as a slide bearing and is provided with friction disks under initial spring pressure axially, which disks effect a frictional damping of pivotal motion for suppressing vibrations and characteristic disturbances. The slide rail is made in one piece, of synthetic material, and is provided with recesses for the pivot bearing, a torsion spring and frictional dampers.
