Abstract
A torque converter in which a torsional vibration damping device is fastened firmly to a turbine hub in such a manner that a hermeticity test can be carried out easily. In the torque converter, a turbine runner is fixed to the turbine hub through a first rivet. The torsional vibration damping device is assembled as a unit independent from the turbine hub and a rolling mass is held in a casing liquid-tightly. The torsional vibration damping device and the driven member are fixed to the turbine hub through a second rivet.
