Claim:
1. A tuned mass vibration damper for a drivetrain of a motor vehicle configured to damp a vibration component of a rotational movement around an axis of rotation comprising: at least one damper mass configured to execute an oscillation depending on the rotational movement to damp the vibration component; and at least one guide component part configured to movably guide the at least one damper mass to enable the oscillation thereof; wherein the damper mass comprises: wherein the at least one damper mass is configured to drive the retaining component part during a movement of the damper mass along a circumferential direction and to allow a relative movement of the retaining component part with respect to the damper mass which results in a change in a radial distance of the retaining structure from the axis of rotation; and wherein the at least one damper mass and the at least one guide component part are configured to prevent the retaining structure and the mating retaining structure from coming in contact with one another when an upper threshold speed is exceeded, wherein the at least one damper mass is guided relative to the at least one guide component part by at least one rolling body that guided on a running path of the at least one guide component part and of the at least one damper mass, wherein the retaining structure and the mating retaining structure or the retaining structure and at least one guide component part are configured and arranged to prevent the at least one rolling body from striking an end of a running path of the respective rolling body.
