The first damper mass 14 is connected to the first damper mass carrier 16 via at least one first spring element 18. The second damper mass 20 is connected to the second damper mass carrier 26 via at least one second spring element 28. In this case, the first damper mass 14 forms in particular a second damper mass carrier 26. Therefore, the first and second vibration damping mechanisms 12, 20 are preferably connected and function in series.
