Abstract
A centrifugal clutch is disclosed. The centrifugal clutch has a first plate provided in a clutch housing, a second plate provided in a clutch boss, a pressure plate capable of being moved close to and away from the first and second plates, and a centrifugal weight arranged to push the pressure plate toward the first and second plates by receiving centrifugal force. The centrifugal clutch is arranged so that torque T transmitted between the first and second plates is temporarily reduced and then increased as an engine rotational speed is increased from a time when an engine is stopped.
