A chassis component has a rotary damper with a housing, a damper shaft rotatably accommodated thereat, a displacing device in the housing, and a magnetic field source. The displacing device has a damper volume with magnetorheological fluid to influence the damping of the rotary motion of the damper shaft relative to the housing. The damper volume is divided into variable chambers by a partition wall connected with the housing and a partition wall connected with the damper shaft. Radial and axial gaps are formed between the partition walls, the damper shaft and the housing. The magnetic field source has a controllable electric coil for influencing the strength of the magnetic field and thus the strength of damping. A substantial part of the magnetic field of the magnetic field source passes through the gaps and influences the gap sections in dependence on the strength of the magnetic field.
