ABSTRACT:
A torsion damping device for an automotive vehicle includes two coaxial parts which are mounted for rotation relative to each other. One of these coaxial parts has through openings and the other incorporates a number of arms, and main resilient members mounted in these through openings bear circumferentially on insert members, being arranged to act through the latter against the arms. Centering members are also provided between two adjacent main resilient members. The centering member comprises a spacer member extending between two of the through openings, together with a resilient member acting between the spacer member and the corresponding arm. The spacer member is divided into two centering fingers, separate from each other but with the resilient centering member extending from one of the centering fingers to the other.
