Abstract
A centrifugal clutch assembly having a resilient restraining means for providing a radially inwardly directed restraining bias to each of a plurality of clutch shoe members is disclosed. The restraining means comprises a coiled spring member circumferentially surrounding and in contact with each clutch shoe member and a rod spring member extending substantially a complete extent of and enclosed within the coil spring member. A coil spring member and the rod spring member each contribute to the radially inwardly directed bias whereby the idle range of the clutch mechanism is increased over the use of either spring member by itself. In this way, overstressing of a spring member is eliminated.
