Abstract
An automatic transmission that is structured such that the first clutch, the third clutch, and the fourth clutch are disposed in an axial direction more toward the speed-reduction planetary gear than the planetary gear unit; friction plates of the first clutch are disposed so as to be offset in the axial direction with respect to friction plates of the third clutch and friction plates of the fourth clutch; and the friction plates of the fourth clutch are disposed such that at least a portion thereof coincides in the axial direction with the friction plates of the third clutch on an inner peripheral side of the friction plates of the third clutch.
