Date May 28, 1995The torsion damper comprises two coaxial masses (1, 2) which are mounted for rotation of one with respect to the other against a torsion damper device (3), which comprises friction member (5) and a damper plate (31) fixed to a reaction plate (21) which is part of one of the masses. The other mass includes a central nose (4) which projects axially and penetrates into central bores of the damper plate (31) and reaction plate (21). A plain bearing is interposed between the said central bores and the central nose (4), while the friction member (5) is mounted in a cavity, the greater part of which is bounded by the damper plate (31) and the reaction plate (21).
