Abstract

The invention relates to an adjustment device (30) for a rotating body (10; 21; 22), in particular a fan (10) of a cooling fan for a combustion engine, or a shaft (21) or a rotor (22) of an electric motor (20), comprising a rotation axis (R), wherein a mass (311; 10; 11; 14) that rotates around the rotation axis (R) can be dislocated relative to the rotation axis (R) by means of the adjustment device (30). The invention further relates to a rotating body (10; 22), in particular a fan (10) of a cooler blower for a combustion engine, or a shaft (21) or a rotor (22) of an electric motor (20), comprising an adjustment device (30) according to the invention.
