Abstract

An automatic transmission includes an input shaft, first, second, third, and fourth planetary gear sets, a plurality of engagement mechanisms, and an output member. The input shaft is rotatably supported inside a transmission case to be rotated by a driving force received from a drive source. The first, second, third, and fourth planetary gear sets are arranged in sequence along an axis line of the input shaft and each include three elements having a sun gear, a carrier, and a ring gear. The plurality of engagement mechanisms each releasably connect two of the three elements with each other or releasably connect one of the three elements to the transmission case. The output member is disposed on outer circumferences of the second and third planetary gear sets and connected to the ring gear of one of the second and third planetary gear sets to output rotation of the input shaft.
