Abstract

A torsional damper device comprises two coaxial parts disposed to rotate relative to one another within defined limits of relative angular movement. One comprises a hub flange and the other two guide rings disposed one on each side of the hub flange. Spacers fasten together the guide rings and elastic means are disposed circumferentially between the coaxial parts, housed in openings in circumferential series in the hub flange and in each guide ring. At least one of the guide rings features U-shaped peripheral stamped portions each associated with one opening, being radially aligned with the respective opening outwardly thereof. A circumferential strip separates each stamped portion and the corresponding opening.
