PROBLEM TO BE SOLVED: To provide a torsional vibration damping device with which an improvement in the binding strength among rotation members at an input side and an improvement in the strength of rotation members at an output side are directed, and to provide a lock up clutch mechanism using the torsional-vibration damping device.SOLUTION: Outer peripheral parts 39 of two sheets of drive plates 26 are fastened and bonded by a bonding means of a rivet 27. A spring receiving recess 50 (spring storage) of a hub plate 24 is formed at the inner side in a radial direction than the bonding position of the rivet 27, and a window part 52 is formed at the inner side in a radial direction than the spring receiving recess 50. Then, two sheets of drive plates 26 are not restricted by the position or the number of bonding means such as the rivet 27, and the hub plate 24, for example, does not need the formation of a circular arc-shaped guide to permit the rivet to escape. |
