A torsional vibration damper includes an input part for introducing a torque, a first cam mechanism, an intermediate element, a compression spring engaged with the intermediate element, a second cam mechanism for discharging a vibration-damped torque, and a frictional element for friction damping. The intermediate element is coupled to the input part via the first cam mechanism such that a relative rotation between the input part and the intermediate element is converted into a linear movement of the intermediate element radially inward or radially outward. The output part is coupled to the intermediate element via the second cam mechanism such that a linear movement of the intermediate element is converted into a relative rotation between the output part and the intermediate element. The frictional element is pressed against the intermediate element or the output part. The frictional element may be movement-coupled to the intermediate element or the output part.
