PROBLEM TO BE SOLVED: To widen a predamper unit, and to shorten axial dimensions thereof.SOLUTION: A damper disc assembly is equipped with a main damper unit and a predamper unit. The predamper unit has: a plurality of outer peripheral side torsion springs 23; a second sub plate 22; a plurality of inner peripheral side torsion springs 24; and a first sub plate 23. The plurality of outer peripheral side torsion springs 23 is engaged with a retaining plate 4 of the main damper unit, and inputted torque. The second sub plate 22 is coupled to an output hub 7. The plurality of inner peripheral torsion springs 24 is engaged with the second sub plate 22 to transmit the torque. The first sub plate 21 actuates the outer peripheral side torsion springs 23 and the inner peripheral side torsion springs 24 in series.SELECTED DRAWING: Figure 5 |
