Abstract:
1. A differential unit comprising: a differential mechanism transmitting a rotational force from an input rotation member to a pair of output rotation members while allowing a differential rotation between the output rotation members; a differential limiting mechanism capable of limiting the differential rotation; a differential lock mechanism capable of locking up the differential rotation, the differential limiting mechanism and the differential lock mechanism being independently provided for independent operation; a differential carrier housing the differential mechanism and the differential limiting mechanism; an annular limiting actuator configured to actuate the differential limiting mechanism and disposed in the differential carrier together with the differential limiting mechanism; an annular lock actuator configured to actuate the differential lock mechanism, the annular lock actuator and the differential lock mechanism being disposed exterior of the differential carrier; a cover externally and detachably attached to the differential carrier, the cover defining an interior cavity housing the annular lock actuator and the differential lock mechanism; and the annular lock actuator being support by the cover.
