A limited slip differential gear mechanism includes a pinion shaft rotating integrally with a differential gear casing, pinion gears attached rotatably to the pinion shaft, side gears engaged with the pinion gears and splined to axles, and a plurality of first and second clutch plates alternately disposed between the side gears and the differential gear casing. A lug portion provided on the inner surface of each first clutch plate engages with the outer surface of the side gear, while a lug portion provided on the outer surface of each second clutch plate engages with the inner surface of the differential gear casing. Concave portions or projections are formed between the first and second plates in contact with each other to define gaps for retaining lubricating oil.
