A differential drive mechanism includes a driven body assembly adapted to drive or permit overrunning of either of two hubs through crowned rollers movable by cup-shaped cages having bottoms frictionally engaging damping bosses of an end cap and an inner flange of an integral body and also engaging friction actuating plugs carried by the hubs. Limited lost motion is provided between the hubs to permit one to be driven while the other overruns.
