Patent ID: 7963381

Claim:
A multi-plate centrifugal clutch, comprising: a first rotating body having a plurality of drive plates; a second rotating body arranged coaxially with the first rotating body and having a plurality of driven plates, the drive plates and the driven plates being alternately arranged in a predetermined direction; a rotatable shaft extending coaxially through the first and second rotating bodies, the rotatable shaft being rotatably fixed to one of the first and second rotating bodies; a pressure plate configured to rotate together with the first rotating body, the pressure plate adapted to move in the predetermined direction to bring the drive plates and the driven plates into frictional contact with each other; at least one centrifugal weight configured to move outward in a radial direction of the pressure plate in response to centrifugal force applied to the centrifugal weight and thereby press the pressure plate in a direction such that the drive plates and the driven plates are brought into frictional contact with each other; a first oil supply path configured to supply oil to the drive plates and the driven plates; and a second oil supply path configured to supply oil to the at least one centrifugal weight.
