The present invention widens the angle and shortens the axial-direction dimension of a pre-damper unit. This damper disk assembly is provided with a main damper unit and a pre-damper unit. The pre-damper unit has a plurality of outer-circumferential-side torsion springs (23), a second sub-plate (22), a plurality of inner-circumferential-side torsion springs (24), and a first sub-plate (23). The plurality of outer-circumferential-side torsion springs (23) are engaged with a retaining plate (4) of the main damper unit and have torque inputted thereto. The second sub-plate (22) is connected to an output hub (7). The plurality of inner-circumferential-side torsion springs (24) are engaged with the second sub-plate (22) and transmit torque. The first sub-plate (21) makes the outer-circumferential-side torsion springs (23) and the inner-circumferential-side torsion springs (24) operate in series. |
