Abstract
An automatic transmission includes two clutches that are disposed such that they overlap in an axial direction and occupy different positions in a radial direction. Each of the two clutches includes a clutch drum, a piston that forms a working fluid chamber for which a portion of the clutch drum serves as a cylinder, a plurality of friction plates that engage the clutch drum, and a cancel oil chamber that is disposed on a rear face side of the piston and that cancels a centrifugal oil pressure that acts on the working fluid chamber.
