Abstract
An automatic transmission () includes first, second, and third planetary gear sets () and a lubricant feed passage (L). The first and second planetary gear sets () form a two-stage planetary gear set (). The third planetary gear set () is adjacent to the two-stage planetary gear set on one axial side of the automatic transmission. The lubricant feed passage (L) feeds a lubricant to a bearing () of the second planetary gear set located on an outer periphery of the two-stage planetary gear set (). The lubricant feed passage feeds the lubricant from a first inlet () to the bearing via a first oil passage () and oil passages () in a pinion shaft. The first inlet () is formed on a side of a carrier body () opposite to the two-stage planetary gear set and on an inner periphery of the automatic transmission.
