ABSTRACT OF THE DISCLOSURE A centrifugal clutch has a pair of clutch shoes pivot- ally mounted on a pivot collar for outward movement under the influence of centrifugal force to drivingly engage a concentri- cally mounted clutch housing. Extension springs bias the swinging ends of the clutch shoes toward retracted position. The pivot collar has a hollow cylindrical sleeve with a pair of nearly cylindrical projections mounted diagonally opposite of each other on the external surface of the sleeve. The cylindri- cal projections are similar to and are located parallel with each other and to the axis of the sleeve and have cylindrical circumferences greater than 180° and less than 360°. A dis- continuous opening is formed on one end of each clutch shoe adjacent the inner edges thereof and have a shape and size com- plementary to the outer cylindrical surfaces of the collar pro- jections. The collar projections are telescopically inserted within the clutch shoe openings to pivotally mount the clutch shoes on the pivot collar. The pivot collar is mounted on a drive shaft for rotation with the shaft. The clutch shoes each include a pair of similar half-shoes sections and an intervening spacer segment sandwiched therebetween. The extension springs extend between adjacent hook ends formed on the shoe spacers to bias the shoes toward retracted position.
