Abstract
In a torsional damper device with an elastic centering member, in particular for automotive vehicle clutches, two coaxial parts are disposed to rotate relative to each other against an elastic member which is adapted to return them to a rest mean position and which is a block of elastic material adapted to bear directly on corresponding shoulders on the coaxial parts concerned. The elastic member has a recess in the median area of each circumferential end.
