The hub part (1) rotates around a rotational axis. The vibration absorber masses (2) are symmetrically positioned in relation to an axis of symmetry going through the centre (M) and are pivoted on pivot axes spaced apart from the rotational axis (3), following the rotational movement (4). Each vibration absorber mass is mounted by two peripherally spaced apart bolts (5) extending parallel with the rotational axis in the hub part. The bolts run on curved paths (6). The outer shape is in the form of a circle arc on an axis of symmetry of the vibration absorber mass going through the centre. The outer shape has a centre displaced outwardly by the pendulum length.
