In contrast to the riveting of the separating sheets 214 to one another, the radially outward-pointing legs 615 are riveted to the carrier part 605 in the tapered flange region 622. The axially opposite legs 615 are each riveted by means of the same rivet 619.

(22) The separating means 708 of the centrifugal pendulum device 700 of FIG. 7 is formed from flat separating sheets 714, which are received on the side parts 712, 713 on the carrier part 705 by means of pins 724 engaging in axially aligned openings 723.
