Abstract
A vibration damper for a torque transmission device comprising a first element and a second element which are rotatable relative to each other around an axis of rotation X; and damping means for transmitting a torque and damping the rotational acyclisms between the first element and the second element. The damping means comprise an elastic blade mounted securely on the first element and provided with a cam surface; and the damper comprises a cam follower carried by the second element and arranged to cooperate with the cam surface. The cam surface is arranged such that, for an angular travel between the first element and the second element relative to an angular rest position, the cam follower exerts a flexion force on the elastic blade producing a reaction force able to return the first and second elements to the angular rest position.
