Abstract
A clutch device for an automatic transmission includes an input member, a first output member, a second output member, a first clutch mechanism formed between the input member and the first output member, a first piston movable in a first axial direction for engaging the first clutch mechanism to transmit rotation torque from the input member to the first output member by receiving oil pressure, and a second clutch mechanism formed between the input member and the second output member radially outwardly of the first clutch mechanism. The first clutch mechanism and the second clutch mechanism are located in axially overlapping relation to each. A second piston is movable toward the second axial direction that is inverse to the first axial direction for engaging the second clutch mechanism to transmit rotation torque from the input member to the second output member by receiving oil pressure.
