Claim 0:
1. A device comprising a body and a set of vibration absorbers mounted on the body, each vibration absorber being capable of oscillating relative to the body between a first and a second position, a first natural frequency being defined for each vibration absorber, at least one vibration absorber having a first natural frequency different from the first natural frequency of another vibration absorber,
each vibration absorber comprising at least one deformation part capable of deforming when the vibration absorber oscillates between its first position and its second position, the deformation part having at least two faces configured to exert a shear force on each other upon deformation of the deformation part, the faces configured to exert a shear force on each other during deformation of the deformation part being configured to rub against each other during deformation of the deformation part.
