In order to dissipate predominantly torsional oscillations in rotating shafts, particularly in the case of passenger vehicle propeller shafts with a relatively high rotation speed, an oscillation damper is proposed which consists of a supporting body (1) having an attachment flange (2) for the purpose of connection to the shaft, a flywheel ring (4) which concentrically surrounds the supporting body (1), and a plurality of rubber springs (5) which are vulcanized in, distributed on the circumference between the supporting body (11) and the flywheel ring (4) and are in the form of segments, additional elements (8, 9, 10) being provided between the rubber springs for radial support of the flywheel ring (4) with respect to the supporting body (1). The additional elements (8, 9, 10), which are constructed in the form of columns and extend axially, consist of dimensionally stable material, have a radial extent which virtually corresponds to the radial distance between the supporting body (1) and the flywheel ring (4) and are supported by relatively thin rubber layers (11, 12) with respect to the supporting ring (1) and the flywheel ring (4). The torsion amplitude of the flywheel ring (4) with respect to the supporting body (1) is limited by means of elastic stops (13, 14 and 16, 17 and 20, 21). <IMAGE>
