Abstract

A torsional damper comprises at least two coaxial parts rotatable relative to one another within predetermined limits. A plurality of circumferentially acting elastic means are disposed between them in the circumferential direction. These elastic means comprise at least one block of elastic material extending in a substantially tangential direction. The or each elastic material block is partially housed, without circumferential clearance in a rest configuration of the damper, in an opening formed for this purpose in a first of the coaxial parts. It is further partially housed, with circumferential clearance in this rest configuration and for at least one circumferential direction, in an opening formed for this purpose in a second of the coaxial parts. The elastic material block carries at least one elastic material peg projecting from it in at least this circumferential direction. Its corresponding circumferential end is at least partly covered by a distribution and retaining plate. This has a notch in its perimeter which is open in the radial direction and through which the elastic material peg passes.
