The projections 20, 19 are formed by outward shearing of sections of the conical portions 15, 17<SP>1</SP> until their outer surfaces are part cylindrical but still  connected to the portions 15, 17<SP>1</SP>. The detent 33 has arms 37, 38 frictionally engaging the cylindrical surfaces 34, 35 of the nut 28 and expander 17. The wheel hub 11 has an internal shoulder 39. The outer surfaces of the shoes 13, 14 are helically grooved to spread lubricant along the hub. Forward rotation of the driver 6.-Forward rotation of the driver 6 by the sprocket 7 and the frictional action of the detent 33 cause the clutch nut 28 to move left along the extension 26 until it locks the hub 11 to the sprocket 7. Cessation of forward rotation.-If the driver 6 ceases to rotate while the vehicle is in forward motion, the detent frictionally slows the nut 28 which moves slightly to the right to unlock the hub which then coasts, the nut 28 remaining stationary. Backward rotation.-Backward rotation of the driver 6 to apply the brake causes the nut 28 to move to the right as rotation of the nut 28 is resisted by the detent, until rotation is prevented by the engagement of the teeth 31, 32. Further backward rotation forces the nut 28 together with the expander 17 to the right thus expanding the brake shoes 13, 14 into frictional engagement with the interior of the hub. Forward rotation resumed.-Forward rotation of the driver 6 causes the nut 28 to move to the left drawing the expander 17 with it by means of the detent 33, until the detent 33 abuts the shoulder 39 of the hub 11.
