Abstract: A motor vehicle door includes an arrester device having a magneto-rheological fluid for holding the motor vehicle door in position, and a coil for solidifying the magneto-rheological fluid that is disposed adjacent to a liquid-tight interior space, with the interior space containing one or more components which can be moved relative to other components in the interior space. A relative movement between these components is slowed down by solidifying the magneto-rheological fluid and the slowing down of the relative movement causes the motor vehicle door to be held in position. The coil is part of a switchable hard magnet which is selected such that a sedimentation-stable, magneto-rheological fluid is obtained. The motor vehicle door may thus be reliably held in a freely selectable position.
