- the friction element 30, in particular comparable to the embodiment of the torsional vibration damper 10 in FIG. 3, can be fastened in a rotationally fixed manner to the intermediate element 16, while the spring element 36 can rotate with the output disk 24.
- a frictional relative movement between the friction element 30 and the spring element 36 can take place.
- a contact region of the spring element 36 designed in particular as a disk spring is formed as a dome on the friction element 30 so that sliding contact with a sharp-edged edge of the spring element 36 is avoided and incorporation of the spring element 36 into the material of the friction element 30 is avoided.
