PROBLEM TO BE SOLVED: To improve a lubrication performance.SOLUTION: A feeding part 30 of an oil garter 20 is partitioned into the first feeding part 42 and the second feeding part 52 by a partition wall 36 in an extending direction of the feeding part 30. Then, a bottom surface 44 of the first feeding part 42 is formed with an upward inclination part 44a becoming an upward inclination as it is faced away from the partition wall 36 and at the same time a bottom surface 58 of the second feeding part 52 is formed with a downward inclination toward a passing opening 38. With this arrangement as above, lubricant oil scraped up by a ring gear 9 is struck against the partition wall 36, guided to the passing opening 37 and fed into a flow passage 60. In turn, the lubricant oil that rides over the partition wall 36 is fed into the second feeding part 52 and fed from the passing opening 38 into the flow passage 60. Further, a flow of the lubricant oil trying to flow in a reverse direction is restricted by the upward inclination part 44a and at the same time a flow of lubricant oil toward the passing openings 37, 38 is promoted by an upward inclination part 44a and the downward inclination of the bottom surface 58.SELECTED DRAWING: Figure 3 |
