PROBLEM TO BE SOLVED: To radially position an input-side damper mechanism with a simple constitution while suppressing abrasion of a positioning portion.SOLUTION: A lock-up device includes a clutch portion, a first damper mechanism D1, a second damper mechanism D2, and a positioning mechanism. Torque from the clutch portion is input to the first damper mechanism D1, and the first damper mechanism is axially movable relative to the clutch portion and attenuates torsional vibration. Torque from the first damper mechanism D1 is input to the second damper mechanism D2, a driven plate as an output portion is fixed to a turbine, and the second damper mechanism attenuates torsional vibration. The positioning mechanism radially positions the first damper mechanism D1 by engaging a claw 39d of a drive plate 39 of the first damper mechanism D1 with holes 48c, 49c of first and second plates 48, 49 of the second damper mechanism D2. |
