FIELD: machine engineering.
SUBSTANCE: device contains the first coil spring (31) and the second coil spring (32) disposed in a circumferential direction between a support arm (11) on the side of the hub disk for the hub (1) disk and the support arm (24) on the side of the intermediate disk for input/output disk (2). The first spring seat (41) and the second spring seat (42) are made of polymeric material. The metal core element (45) supports two ends of the coil springs (31), (32). Two saddles (41), (42) of the spring comprise a seat piece (43) and a protruding piece (44). The element (452) of the metal core of the protruding piece of the element (45) comprises a piece (452) with low rigidity. The high rigidity piece (452b) is formed on the far side of the seat piece (43).
EFFECT: increasing the wear resistance of the protruding piece and the coil spring.
