  "textContent": "A differential case (23) is therein provided with a plurality of rotating discs (38) that are spline-coupled to an outer peripheral side of a right side gear (35), and a plurality of non-rotating discs (39) that are respectively arranged between the respective rotating discs (38) and are non-rotatable relative to the differential case (23) and are movable in a left-right direction. A pressure ring (43) that presses the non-rotating discs (39) toward the rotating discs (38) is disposed between a right retainer (41) positioned in the right side gear (35)-side and the non-rotating disc (39). The right retainer (41) is therein provided with a piston accommodating part (41D) in a position facing the pressure ring (43) in the left-right direction. The piston accommodating part (41D) is therein provided with a piston (46) that is displaced by hydraulic pressure to press the non-rotating discs (39) against the rotating discs (38) through the pressure ring (43).",
