Abstract:
1. A planetary gear train of an automatic transmission for a vehicle comprising: a first shaft receiving torque of an engine; a second shaft disposed in parallel with the first shaft at a predetermined distance; a first planetary gear set on the first shaft, and including a first rotation element selectively connected to the first shaft, a second rotation element selectively connected to the first shaft and selectively connected to a transmission housing, and a third rotation element; a second planetary gear set on the second shaft, and including a fourth rotation element connected to the first rotation element through a first externally-meshed gear and selectively connected to the first shaft through a second externally-meshed gear, a fifth rotation element connected to the third rotation element through a third externally-meshed gear and directly connected to an output gear, and a sixth rotation element selectively connected to the first shaft through a fourth externally-meshed gear and selectively connected to the transmission housing; three transfer gears forming the first, second, third, and fourth externally-meshed gears respectively; and frictional elements including clutches selectively connecting the first shaft to rotation elements of the first and second planetary gear sets and brakes selectively connecting rotation elements of the first and second planetary gear sets to the transmission housing, wherein the three transfer gears comprise:
