The invention relates to a vibration damper for a clutch friction disc (1) including: an input element and an output element, rotatably movable relative to one another about an axis of rotation X; damping means for transmitting a torque and damping the rotational deviations between the input and output elements; the input element including two flanges (12, 13), fixed to one another for conjoint rotary movement, arranged on either side of the damping means and thus defining a cassette for housing said damping means; the damping means comprising a resilient blade (22), fixed to one of said input and output elements for rotation therewith, and provided with a cam surface (23). The damper comprises a cam follower (24), supported by the other one of said input and output elements, and arranged such as to engage with said cam surface (23). The cam surface (23) is arranged such that, for an angular displacement between the input element and the output element relative to an angular rest position, the cam follower (24) exerts a bending force on the resilient blade (22) producing a reaction force capable of returning said input and output elements towards said angular rest position. |
