摘要： A wet friction plate of a hydraulic clutch or hydraulic brake for an automatic transmission having a reduced friction resistance in a non-engaged state. A plurality of friction materials disposed in an annular shape with a plurality of radial oil passages each provided between the adjacent friction materials are mounted at two radially inner and outer stages on a surface of a friction plate of a wet hydraulic clutch of an automatic transmission. The friction materials are brought into contact with an annular separator plate to transmit a torque. Inner peripheral edges of each of the friction materials are formed into a V-shape toward a radially outer side. Thus, when the friction plate and the separator plate are in non-engaged states, a lubricating oil remaining between both the plates can be guided effectively to the radial oil passages by a centrifugal force and discharged to the outside, and a friction resistance due to the dragging of the lubricating oil can be reduced to avoid the generation of an energy loss.
