Abstract

A recess is formed on the side surface of output-side cams on the right side with through holes being formed on the sidewall of the case body of the differential case at positions corresponding to the recesses. An annular member is placed on the case body so as to be capable of moving, and projections are provided on the annular member so that they can be inserted into and pulled out of the recess via the through hole. The differential case and the right side output cam are rigidly joined by inserting the projection into the recess on the right side output cam through the through hole and thus the input-side block is not operated. Therefore, a power force is not transmitted to the left side output cam, and thus the differential function of the left and right drive wheels can be suspended.
