摘要

A torsional damper (12) comprising an input part (20) with a piston (24) having a guide disc (28) and an output part with a ring-shaped plate (36), and further comprising a series of radially inwardly projecting tabs (44) engaging the edge (42) of a peripheral rim (40) of the plate (36). The rim (40) comprises a series of notches (48) angularly spaced to match the tabs (44) of the first part and sized so that said tabs (44) can be axially inserted into the notches (48) and the second part (22) can be axially retained within the first part (20) by mutually rotating said two parts through a fraction of one turn, as in the case of a bayonet joint.
