ABSTRACT:
The differential unit with a limited slip differential mechanism of the present invention comprises a planetary gear mechanism for torque distribution of drive torque inputted to an input shaft from an engine between a front drive shaft and a rear drive shaft, and a multiple disc clutch for limiting differential rotation of the planetary gear mechanism, wherein, when a clutch plate receiving clutch engaging force applied to the multiple disc clutch is fixed to a side surface of a planetary carrier of the planetary gear mechanism, pins are formed on the ends of bolts for fixing the planetary carrier, and positioning and fixing is carried out by fitting the pins into check holes formed in the clutch plate.
