Claim:
1. A torque converter having a torsional vibration damping device, comprising: a turbine hub that is connected to a turbine runner; a driven member of a lockup damper that damps torque pulses transmitted through a lockup clutch; and a rolling mass that is held in a casing of the torsional vibration damping device sealed liquid-tightly in a manner to be oscillated by the torque pulses applied to the turbine hub; wherein the driven member and the torsional vibration damping device are connected to the turbine hub; wherein the turbine runner is fixed to the turbine hub through a first rivet; wherein the torsional vibration damping device comprises a rotary member; wherein the torsional vibration damping device is assembled as a unit independent from the turbine hub; and wherein the rotary member and the driven member are directly fixed to the turbine hub through a second rivet.
