A differential gear mechanism of the limited slip type is provided. The mechanism includes a clutch, including a plurality of discs (31 and 33), and a cam mechanism including a main cam member (43) and an intermediate cam member (45). The intermediate cam member is splined to the side gear (19), such that axial forces are not transmitted to the side gear. The main cam member (43) defines a set of internal gear teeth (81), engaging an externally toothed member (79) of an acutating mechanism (71). The arrangement of the cam members and the provision of the gear teeth on the inner periphery of the main cam member results in a differential gear mechanism having a substantially reduced "bearing span", combined with a reduced casing diameter.
