Abstract
The invention concerns a torsional damper (23) comprising an input element and an output element coaxial and movable in rotation relative to each other counter at least to an compression spring (300), wherein the two adjacent transverse parts, with radial orientation, associated with the input and output elements each comprise a housing (306-308, 302) receiving the spring (300) whereof the opposite ends are capable of co-operating with the supporting end surfaces (316-318, 304) which define the two housings to operate between the two elements; the length (LF) of each of the two associated housings (306-308, 302), separating the opposite supporting end surfaces, being greater than the length (LR) of the spring (300) at rest.
