<p>PROBLEM TO BE SOLVED: To properly lubricate a bearing of a compound gear and a pinion gear by scattering of a lubricant discharged to the external from a rotating shaft, to an outer peripheral side by centrifugal force.SOLUTION: A lubricant flowing out from a radial oil passage 62 and scattering to an outer peripheral side by centrifugal force through a thrust bearing 34, is received by an oil receiver 64, and guided to a pinion lubricant passage 74 by a tapered cylindrical side wall portion 68, thus a pinion gear 22 can be properly lubricated by the lubricant. A part of the lubricant received by the oil receiver 64 escapes to the outer peripheral side from a plurality of through holes 72, so that a ball bearing 54 of a compound gear 52 can be properly lubricated by the lubricant.</p> |
