Abstract
A diametrical slot is provided in the bottom of the cup-shaped support of a tensioning roller assembly, for receiving a clamping bolt. A leaf spring is mounted in the bore and has a bending zone engaging the bolt, the leaf spring extending from on both sides of the bending zone to roll sections adapted to roll on and off the bore surface of the support so that, as tension is increased by the displacement of the bolt in the slot, a greater portion of the leaf spring rolls off of the bore surface of the support.
