Wetting centrifugal clutch

PROBLEM TO BE SOLVED: To prevent or suppress occurrence of the slapping sound generated due to the collision of a support shaft with a weight by forming an oil supply path supplying lubrication oil to an insert hole of the weight inserted by the support shaft and reducing the wear of the contacting part between the support shaft and the weight without increasing the number of parts in a wet centrifugal clutch. SOLUTION: The wet centrifugal clutch is equipped with the support shaft 3 provided on a drive plate 2 integrally rotating with a crank shaft, and the weight 4 pivotably supported by the support shaft 3 having the insert hole 40 inserted by the support shaft 3. The weight 4 consists of laminated board materials 41, 42. In the board material 42 with a groove, the groove 43 reaching the insert hole 40 is formed on the side surface 42b in the laminating direction and the oil supply path 44 is formed for supplying the lubrication oil pressurized by the centrifugal force to the insert hole 40 with the through-hole formed by the board material 41 covering the groove 43 and the groove 43 from the laminating direction.
