PURPOSE: To eliminate an oil pump by providing an oil passage for connecting chambers to each other, an air passage for connecting chambers to each other and an air pump for pressure-feeding oil into a chamber. CONSTITUTION: Oil flows through an oil passage 20 connecting housing chambers 12, 16, and the oil is pressure-fed from the chamber 16 into the chamber 12 by the rotation of a differential gear 18. An air passage 26 is connected to an air pump 28. By pressure-feeding air from the chamber 16 into the chamber 12 through the air passage 26, the oil is fed from the chamber 12 into the chamber 16 through the oil passage 20 under pressure. Thus, an oil pump can be eliminated. |
