Abstract
An improved overrunning clutch roller energizing spring of the type that has a series of flat leaves forming V's with energy storing folds or pleats at the peak of each V. The front and rear leaves of the spring each have an integrally formed end loop with a diameter greater than the height beyond which the spring should not be compressed. The loop diameter is less than the space differential available between the spring pleats and the side rails. When the spring compresses back toward the roller pocket base, the loops hit on each side of the spring, preventing the spring from compressing further than its solid height. The end loops do not hit or rub on the spring pleats, and prevent the spring pleats from rubbing on the pocket side rails.
