Abstract
A torsion damper, especially for a motor vehicle clutch, is of the kind which includes a friction cassette, i.e. a unitary sub-assembly comprising a friction assembly, which includes a guide ring, a spacing ring having at its outer periphery at least one axially oriented projection, at least one drive ring interposed axially between the guide ring and the spacing ring. A spring causes the drive ring to be gripped between the guide ring and the spacing ring, and this spring bears on a closing ring which is arranged on the side of the guide ring opposite to the spacing ring, and the closing ring is connected to the axial projection of the spacing ring.
