ABSTRACT:
A torsional damper device comprises two parts disposed to rotate relative to one another within defined limits of relative angualr movement. Such relative angular movement is resisted by elastic members each of which is disposed in a housing formed by holes in said parts. At least one bears in the circumferential direction and through the intermediary of a chock on the edge of the corresponding hole in one part. Opposite the other part, the chock has a recess such that on relative angular movement between the parts, this other part may become displaced in the circumferential direction beyond the point of contact of the chock on the corresponding edge of the hole in the first mentioned part.
