Abstract
A roller clutch improves control of the spring at the point where it attaches to the cage. No change is made to the spring, nor to the process by which it is installed to the cage. Instead, the cage cross bar over which the mounting fold of the spring is inserted is strategically thickened so as to spread the leaves of the spring mounting fold, and put it under a preload or tension. This serves to hold the rest of the spring more firmly in position.
