A reversible unidirectional clutch of the hyperboloidal type having an inner race whose surface approximates a hyperboloidal, and an outer race formed of a super derivative forming a volume therebetween for disposition of thurst transmitting rollers. The engagement direction of which may be reversed with reversing the skew of the thurst transmitting rollers allowing rotation of the inner and outer race in both directions or, selectively, in either one direction or the other, or capable of freewheeling each race in both directions.
