Abstract
The friction means acting between the two rotary parts constituting a torsion-damping device comprises at least one annular component which is engaged by means of an axial bearing surface with an axial bearing surface of one of the rotary parts and which, by engagement means, is capable of being connected in rotation to the one rotary part over at least one range of the angular movement between the rotary parts. According to the invention, the annular component is opened circularly by means of at least one slit, and elastic means are associated with it which permanently stress it radially in the direction of the axial bearing surface of the one rotary part.
