Abstract

A torsional vibration damper comprises an input side and an output side which are arranged rotatably around an axis of rotation, an intermediate plate, and two elastic elements which are arranged on different circumferences around the axis of rotation, where the first elastic element is set up to transmit a power from the input side to the intermediate plate and the second elastic element is set up to transmit a power from the intermediate plate to the output side. Furthermore, the torsional vibration damper includes a single-piece retainer to support the first elastic element on a radially outer surface, while the retainer includes a contact element for engaging with one end of the first elastic element.
