Abstract
A torsional damper device comprises a first coaxial part in the form of a hub flange formed with circumferential slots and a second coaxial part in the form of two guide rings disposed one on each side of the hub flange. Spacers passing through the slots fasten the guide rings together. Relative angular movement between the first and second coaxial parts is permitted within predetermined limits defined by cooperation of the spacers with lateral edges of the slots. Circumferentially acting elastic members are disposed between the first and second coaxial parts to urge them into an idle configuration. At least one elastic abutment member is carried by one of the coaxial parts and selectively deployable between one of the spacers and at least one of the lateral edges of the associated slot, in order to resist elastically abutment of the spacer against this edge.
