In drawing Figures 1-4, an improved drive clutch 3 that is simple and inexpensive to manufacture has a pulley 5 bored out for a slip fit with a steel ring 6. Two ball bearings 7 in the bore of ring 6 permit the composite pulleyhing subassembly to rotate on shaft 8 freely. The internal diameter of pulley 5 is broached at 9 to form a tooth portion for a rectangular key 11 and elastomer pad 12 which are disposed therein side by side. Ring 6 is milled at 14 with a keyway cutter to retain key and pad 11, 12 in place on assembly of pulley 5 with ring 6.
