Abstract
A wet multidisk friction clutch is constructed of a plurality of driving friction disks connected to an input shaft and a plurality of driven friction disks connected to an output shaft and arranged alternately with said driving friction disks, whereby power is selectively transmitted by frictional engagement between said driving friction disks and said driven friction disks. Each of said driving friction disks comprises a metal core and friction linings applied on opposite sides of said metal core and is partly cut off in a radial direction to define end portions, thereby forming a partly-open annular shape.
