摘要： A wet-type friction clutch plate surely keeps lubricant on a frictional slide face, stabilizes frictional torque transmission, and suppresses shuddering noise. The wet-type friction clutch plate (1) has the frictional slide face (9) on which a grid of grooves (11) is formed. The frictional slide face frictionally engages with an opposite clutch plate. At least one of the sectional shape and plan shape of each of the grooves is configured to provide the frictional slide face with a null-v characteristic that null increases with an increase in v to prevent self-excited vibration during frictional engagement of the wet-type friction clutch plate with the opposite clutch plate, where null is a coefficient of friction on the frictional slide face and v is a relative rotational speed of the wet-type friction clutch plate relative to the opposite clutch plate.
