Abstract
A torsion damper device comprises two coaxial parts, a circumferentially acting resilient element, and a friction device which acts in an axial sense between the two coaxial parts. The friction device includes a friction ring which is in contact with a first friction surface. The friction device is a unitary assembly which comprises at least one element of elastic material. The friction ring is secured over at least one of the faces of the elastic element. This unitary assembly is interposed, so as to be gripped axially, between the first friction surface and a second surface, while an anti-wear element acts between the elastic element and the second surface.
