Abstract
A torsional damper comprises two parts mounted to rotate relative to one another against circumferentially acting elastic means disposed between them. These elastic means include at least one elastically deformable arm fastened at one end to one rotating part so as to rotate therewith. Its other end is unrestricted, and is formed with a shoulder whereby it can engage with a shoulder provided for this purpose on the other rotating part. The or each elastically deformable arm and its support are integral parts of an appropriately shaped flange. An application of the torsional damper is to friction clutches for automotive vehicles, for damping torsional vibration.
