Abstract: A vibration canceler for use on the outer circumference of a shaft rotating about an axis and including two enlargements. The vibration canceler includes half-shells which can be pressed on to the outer circumference of the shaft. The half-shells are joined to at least two inertial masses formed as circle segments by elastic elements which are deformable in a circumferential direction. The inertial masses are joined together by retaining elements. The inertial masses are hingedly joined by link elements and can be restrained in a ring shape by at least one lock element.
