Abstract
This differential apparatus has a differential casing rotated by an engine, side gears on an output side arranged within the differential casing and spline-connected to output shafts, pinion gears for connecting the gears, storing holes for slidably and rotatably storing the gears, a thrust block for receiving thrust forces of the output shafts, washers, respectively opposed to the gears and movably arranged with respect to the thrust block in an axial direction, and a spring for pressing the washers, against the gears, and giving frictional torque to said gears. Accordingly, no thrust forces of the output shafts are inputted to the washer members and the spring and initial torque is released from influences of the thrust forces of the output shafts so that stable differential limiting characteristics can be obtained.
