Abstract
A centrifugal clutch comprises a driving plate having oppositely facing surfaces secured to an input shaft operatively connected to a driving source, a cylindrical bottomed drum detachably secured to an end, projecting from the input shaft, of an output shaft concentrically and relatively rotatably disposed within the input shaft, the cylindrical bottomed drum surrounding the driving plate, and a plurality of clutch springs each connected to each of a plurality of shoes which are supported on the plate for movement toward and away from an inner peripheral surface of the drum respectively by a plurality of stub shafts parallel to the input shaft, the clutch spring providing a spring force in a direction away from the inner peripheral surface of the drum. In the centrifugal clutch, a group of the shoes and clutch springs having respective weight and load which are set to transmit a relatively large torque between the input shaft and the output shaft are arranged closer to the closed end of the drum, and another group of shoes and clutch springs having respective weight and load set so as to transmit a relatively small torque between the input shaft and the output shaft are arranged closer to an opened end of the drum.
