PURPOSE:To eliminate the necessity for setting a pump for circulating lubricating fluid, by feeding the lubricating fluid scraped with a gear to a lubricating fluid cooler provided in a lubricating fluid path by a kinetic energy. CONSTITUTION:Lubricating fluid 8 scraped up in the direction of an arrow head A by a ring gear 4 is guided by a guide plate 15 to reach an outlet 9 and supplied to a lubricating fluid path 11 via an accepting member 17. While a low pressure is generated in the part of an inlet 10 of the lubricating fluid 8 by rotary action of the ring gear 5, as a result the fluid 8 causes a flow from the outlet 9 toward the inlet 10 in the lubricating fluid path 11, and the lubricating fluid 8 in a housing 2 is heat exchanged and cooled by a cooler 13 provided to the half way of the lubricating fluid path 11. |
