Abstract
A torsional vibration damper for a lockup clutch of a hydrodynamic torque converter is provided with a drive-side damper element which is in operative connection with energy accumulators of a damping device and is provided with a driven-side damper element serving to support the energy accumulators in the circumferential direction. The individual energy accumulators are connected with one another by sliding elements which are movable in the circumferential direction along a guide path. The guide path is accommodated at one of the damper elements and a securing device for securing against axial movements of the sliding elements is associated with the guide path. This securing device is formed at the side of the guide path which faces the sliding elements and has a positive engagement with at least one of the sliding elements.
