Abstract
A wet-type multiple disc clutch comprises a clutch plate set having a plurality of friction plates and a plurality of separator plates alternately interposed between a clutch case and a clutch hub. An oil pressure piston slidably retained in a cylinder chamber is disposed between inner and outer cylindrical members of the clutch case and serves to fasten the clutch plate set. A canceler for defining a centrifugal oil pressure cancel chamber between the oil pressure piston and the clutch case is secured on the inner cylindrical member of the clutch case through a stop ring. A detention portion is provided on the canceler for preventing the stop ring from falling out of position.
