Abstract
A torsion damping device comprises at least two coaxial parts mounted to move circumferentially relative to one another against the action of elastic units. Inside a coil spring of one elastic unit a stiffer elastic means is housed, comprising in the central zone of the said unit a block of relatively rigid plastic material and two elastic pads each disposed at one of the circumferential ends of the said unit with a predetermined clearance relative to the block.
