Abstract
A torsional damper device comprises coaxial first and second parts which rotate relative to each other to a limited degree. The first part comprises two substantially parallel annular flanges and pivoted base members. Two parallel plates on the second part are disposed axially between the two flanges. They have at least one pair of radial arms comprising parallel and substantially circumferential fingers. Springs are disposed substantially circumferentially between the base members. The base members comprise on a surface opposite that in contact with the respective spring rounded recesses in which the fingers engage on relative rotation between the two coaxial parts. A rotational coupling device constrains the plates to rotate together and establishes a circumferential corresponding relationship between the radial arms and their fingers.
