The inner surface of the flywheel Iû has annular portions I2 and I3, at opposite 30 substantially an integral part or rigid unit avoid ing moving elements and especially the use of springs, bolts, collars, and pins; requires no ad justing and cannot wobble or wear, thus elimi nating play or backlash, is air-cooled and will erally designated I4 such plate being connected to a hub member I5 as by means of rivets IB, 35 not squeak, chatter, or jerk, but will give a smooth operation, adding to the life of the 1in and the hub member in turn is fastened rigidly ings and eliminating stripped gears or broken in any suitable manner to the shaft II as at l1 axle shafts due to sudden jerks. and its fastening is augmented by a bolt I8 pass Furthermore, the improved clutch' is very light ing through the h‘ub and through the shaft.
