    摘要: An automatic transmission includes a thrust bearing A disposed between a third sun gear of a third planetary gear mechanism and a second sun gear of a second planetary gear mechanism. Accordingly, transmitting a thrust load acting on the second sun gear of the second planetary gear mechanism from the thrust bearing to an input shaft via the third sun gear of the third planetary gear mechanism can avoid, as much as possible, a case where the thrust load is transmitted from the third planetary gear mechanism to the input shaft via a fourth planetary gear mechanism, and reduce friction loss of multiple thrust bearings interposed among elements or the like of the third planetary gear mechanism and the fourth planetary gear mechanism.
