A torsional vibration damper with a receptacle for several absorber masses pivotally held relative to the receptacle disposed around an axis of rotation in radial and circumferential direction. To be able to increase the mass of the absorber masses, the absorber masses have outside contours formed by several outside contour radii that remain within the receptacle over their entire swivel angle, and swivel over the entire swivel range near the outer circumference of the receptacle.
