PURPOSE:To make a transfer clutch compact without the drive feeling and control stability of a vehicle being deteriorated, by arranging an oil pump and a clutch coaxial with a rotary shaft, and by aligning them radially of the rotary shaft. CONSTITUTION:A pump casing 15 is splinedly fitted to a sheath shaft 5', and is provided with a clutch 32 on the outer diameter side of the casing 15. An oil pump 14 stored between both axial ends of the clutch 32 is provided on the inner diameter side of the casing 15. A transfer clutch device 13 is driven by sheaths 5, 5', or more specifically by the differential speed between a front wheel output shaft 4 and a rear wheel output shaft 6. A discharge oil from the oil pump which discharges oil at a pressure in accordance with this differential speed is received through a passage, and therefore, the engagement degree between the output side 4 and the side 6 is adjusted to restrain the differential speed by means of the clutch 32. |
