PURPOSE: A clutch plate for an automatic transmission clutch is provided to secure the smooth discharge of chips caused by abrasion by using an improved shape of oil groove. CONSTITUTION: A clutch plate(30) for an automatic transmission clutch comprises an oil groove(33). The oil groove is formed along the circumferential direction of the clutch plate. The oil groove is formed to accommodate an inlet(33a) having a bigger cross section than that of an outlet(33b). The depth of the oil groove in the outlet is formed to be deeper than that of the inlet. The both sides of the oil groove are formed to be opened to the inner and outer sides of the clutch plate. The gap between each groove is formed to have an outlet portion(L2) having larger length than that of an inlet portion(L1). |
