ABSTRACT:
In a wet type multiple disc clutch for automatic transmission, a series of driving discs or plates and driven plates rotate on a clutch hub of a hollow cylinder. This clutch hub is made by press forming, and has at least one cut portion with which inward projections formed in the driving plates are engaged so that the driving plates rotate together with the clutch hub. The clutch hub is further provided with an inwardly projecting annular barrier member fit in the internal circumference of the clutch hub for directing lubricating oil through the cut portion to the friction surfaces of the driving plates and the driven plates by preventing the oil from spreading away. For example, this barrier member may take the form of a snap ring retained in an annular groove formed in the internal circumference of the clutch hub, or a cylindrical member with an inward flange inserted into the clutch hub.
