PURPOSE:To feed lubricating oil uniformly on the whole surface of each clutch, in accordance with the centrifugal force action by forcibly feeding the lubricating oil in a differential gear box onto the inner periphery of a multipledisc clutch, passing through the inside of an axle, by an oil pump which is applied with the driving power of a differential gear. CONSTITUTION:The lubricating oil in a box 5 is suction-pressurized by an oil pump 6 driven by a rotary transmission means 8 for transmitting the revolution of a differential gear 1, and introduced into a peripheral groove 9 formed in the slidable part 2a between an axle 2 and the box 5. Further, the lubricating oil introduced into the peripheral groove 9 is introduced into a cavity 12 through the first radial passage 11 which is opening-formed on the axle 2. Further, a space 15 is filled with the lubricating oil which passes through the cavity 12, and the lubricating oil is introduced into the cavity 13 of an axle 3, and further introduced into the inner periphery of a multipledisc clutch 4 through the second radial passage 14. The lubricating oil which reaches the inner periphery of the multipledisc clutch 4 is forcibly supplied by the hydraulic pump 6, and applies a centrifugal action and uniformly lubricates the whole surface of each clutch plate.
