ABSTRACT:
A centrifugal clutch for a vehicle includes a clutch housing having friction plates, a clutch boss having clutch plates, a pressure plate, and roller weights that press the pressure plate in a direction such that the friction plates and the clutch plates are brought into frictional contact with each other when the roller weights receive a centrifugal force. The vehicle power unit includes a main shaft which has an oil supply passage formed therein. The clutch includes a first oil supply path that supplies oil via the oil supply passage to the friction and clutch plates. The clutch includes a second oil supply path that supplies oil via the oil supply passage to the roller weights. The first and second oil supply paths are formed individually to allow independent adjustment of oil supply to each path.
