Abstract: An anti-overload centrifugal clutch including a centrifugal clutch having a clutch drum secured to a driving shaft thereof and a group of centrifugal clutch shoes engaged with a driven shaft for contact with and movement away from the clutch drum. A group of centrifugal members are engaged with the driving shaft which are respectively forced to embrace the driven shaft by the action of an associated spring. The centrifugal members release this embrace when the rotation of the driving shaft reaches a predetermined rotational speed.
