<p>PROBLEM TO BE SOLVED: To provide a lubrication structure of a planetary gear device in which a thrust bearing can be assembled to a rotating shaft, and can improve the supply efficiency of a lubricant supplied to a pinion gear more than before.SOLUTION: Since a first thrust bearing 32 is assembled so that apexes 32d of a first race 32a and apexes 40e of a center hole 40d of an oil receiver 40 differ from each other in phases around a rotating axial line O, the apexes 32d of the first race 32a are thereby arranged at portions between the respective apexes 40e of the center hole 40d which are relatively small in diameters at the oil receiver 40. Therefore, the apexes 32d approximate the oil receiver 40 side, and a peripheral portion of the apexes 32d of the first race 32a can be laminated on the oil receiver 40 in a rotating axial line O direction. By this constitution, a lubricant scattered from the first race 32a is suitably received by the oil receiver 40, and the supply efficiency of the lubricant supplied to a pinion gear 22 is improved.</p> |
