  • Patent number: 5680920
    Abstract: A centrifugal clutch for a power-drive working tool, such as a chain saw, includes a hub (10) adapted to be operatively connected to a drive shaft of an engine, and at least two clutch shoes (13) operatively connected to the hub and radially movable in order to, when actuated by centrifugal force, engage a clutch drum radially surrounding the shoes against the action of a resilient member (16) striving to disengage the shoes from the drum. Each of the clutch shoes is slidably connected to a spoke (12) made integral with the hub. Each of the spokes has a cross-section including two integral, laterally-displaced rectangular portions (12a, 12b). Each spoke is slidably received in a complementary recess formed in a clutch shoe, whereby mutual lateral guiding of the spoke and the clutch shoe is insured.
