Abstract
An automatic transmission is provided, which includes a double-sun-gear-type planetary gear set including coaxial first and second sun gears, a ring gear, a pinion meshed with the sun gears and the ring gear, and a carrier supporting the pinion and having a pinion shaft and a carrier body. The carrier body includes first and second plates supporting the pinion shaft, a coupling part coupling the first and second plates, and a center plate extending inward in radial directions of the gear set from the coupling part by passing between the sun gears, and coupled to a rotational member. An inlet port is formed at an inner circumferential end of the center plate, and a center plate oil path extends radially outward from the inlet port. A lubricant oil supply path communicates with a bearing from the inlet port through the center plate oil path.
