Abstract
A torsional damper device suitable for automobile vehicle clutch disks. The torsional damper device comprises two coaxial parts disposed to rotate relative to one another within defined limits of relative angular movement. Friction devices are inserted axially between the coaxial parts and comprise a pressure ring which is acted on by an elastic clamping lug outside the friction area of the pressure ring. This enables the overall size, especially the axial dimension, to be reduced.
