ン装置。 a substantially cylindrical axle housing, a rear axle serving as a drive shaft having disc-shaped flanges disposed within the axle housing and protruding from both ends of the axle housing, inner surfaces of both ends of the axle housing, and an outer periphery of the rear axle. each cylindrical wheel hub, which has one end fixed to the flange portion and the other end fixed to the brake drum, and accommodates both ends of the axle housing therein; Two tapered roller bearings are arranged between the inner circumferential surface of each wheel hub and the outer circumferential surface of both ends of the axle housing, and the load applied to each rear wheel is transferred to the axle through the bearings. In a fully floating rear axle that is supported by a housing so that no load other than driving or braking torque is applied to the rear axle, the inner surface of the flange portion is further outwardly than the outer peripheral surface of both ends of the axle housing. an oil slinger protruding toward the outer peripheral surface of the axle housing; an oil reservoir groove formed in a portion of the upper outer peripheral surface of the axle housing near the tip of the oil slinger; and a bottom surface of the groove and the inside of the axle housing. a through hole communicating with the oil seal, the oil seal closes the through hole from the inner surface of the axle housing, and when the internal pressure in the wheel hub and the weight of the oil accumulated in the groove act, the oil seal closes the through hole from the inner surface of the axle housing. A fully floating rear axle leakage oil return device featuring a lip that bends toward the side.
