Abstract
A torsion damper, especially though not exclusively for a motor vehicle clutch, is of the kind having two coaxial parts, namely a primary coaxial part and a secondary coaxial part, which are mounted for rotation one with respect to the other against the action of at least one spring which is arranged with its length extending generally circumferentially along an arc of a circle. The spring comprises a succession of at least two straight portions continuous with each other and defining median lines, each of which is tangential to the arc of a circle.
