Zusammenfassung:An automatic transmission includes a clutch device having a clutch hub, a clutch drum, a friction plate, a piston, and a hydraulic chamber. The clutch drum includes an outer-side cylindrical portion, a disc-shaped first radial-direction portion extending to the radial-direction inner side, an axial-direction portion extending from the first radial-direction portion in the axial direction, and a disc-shaped second radial-direction portion extending from the axial-direction portion to the radial-direction inner side. The piston includes a pressing portion disposed between the first radial-direction portion and the friction plate side, and a disc-shaped piston radial-direction portion extending to the radial-direction inner side from the pressing portion. The hydraulic chamber is provided on the radial-direction inner side from the axial-direction portion and on the non-friction-plate side of the piston radial-direction portion. A comb-teeth portion is provided at a radial-direction intermediate portion of the piston radial-direction portion. The axial-direction portion and the piston radial-direction portion intersect with each other in a comb-teeth shape.
