Abstract
A centrifugal clutch is provided having a drive member having a rotor and at least one shoe which is radially displaceable as a result of centrifugal force. A clutch drum is oriented coaxially with the drive member having a circular or cylindrical portion for engaging the shoe. The clutch drum is provided with a central hub and an end wall extending between the central hub and the circular or cylindrical portion. The end wall is integrally formed of a sheet metal stamping provided with a plurality of fan blades circumferentially spaced about the central axis and integrally formed in the end wall by showing a radially extending slit into the end wall and bending the adjacent sheet metal axially outward to define a fan blade and an adjacent vent opening.
