Abstract

A torsional damper device comprises an intermediate member responsive to centrifugal force. At low values of torque, beyond a predetermined critical rotation speed, it causes to become operative an elastic intermediate member which is normally inoperative at such low values of torque. This intermediate member comprises at least one flange which, by way of a toothed portion, is selectively interlocked with the hub. By way of a bearing lug, it is adapted to act on the elastic member concerned.
