ABSTRACT:
A torsional damper device suitable for friction clutches, especially those for automotive vehicles, comprises two parts disposed to rotate relative to one another within defined limits of relative angular movement. Such relative angular movement is resisted by elastic members each of which is disposed in a housing formed by holes in said parts. Associated with at least one of the elastic members is a respective bearing member disposed in the axial direction between at least one circumferential end of the elastic member and one of the coaxial parts. The bearing member has, perpendicular to the axis of the assembly, at least one arm through the intermediary of which it bears axially on the coaxial part concerned.
