Abstract
An automatic transmission has an input shaft and an output shaft provided parallel to the input shaft. Above the input shaft is provided a pair of planetary gear mechanisms, an output gear supported on the transmission casing, and two input elements for inputting to the pair of planetary gear mechanisms. The input elements are spaced apart in the direction of the shafts, and the pair of planetary gear mechanisms and the output gear are provided in the space between the input elements. The planetary gear mechanisms are preferably provided respectively facing each side of the output gear with the output gear in the middle. The output gear preferably functions as a connecting member to operably connect with a rotational member of one of the planetary gear mechanisms. The transmission comprises a plurality of frictional engagement elements for selectively operating the planetary gear mechanism according to the driving condition of the vehicle. These engagement elements are preferably clutches of a novel configuration.
