A torsion damper, in particular for a motor vehicle clutch, comprises two coaxial parts, namely a primary coaxial part and a secondary coaxial part which are mounted for relative rotation against the action of springs, with friction member also being arranged to act between the two coaxial parts. The friction member comprise a radially acting friction ring in the form of a sleeve, meshing, with a clearance, with one of the coaxial parts, together with a radially acting spacing ring, which is coaxial with the friction ring and which engages either the outer or the inner periphery of the latter, the spacing ring being mounted on the other one of the coaxial parts for rotation with that part.
