An adjusting mechanism includes a first sub-assembly, a bolt disposed on the first sub-assembly and a second sub-assembly. The bolt is configured to receive a force in a radial direction relative to an axis of the bolt. The second sub-assembly is mounted so as to be rotatable relative to the first sub-assembly by means of the bolt. The rotatability of the second sub-assembly relative to the first sub-assembly is configured to be reduced by a positive connection created using plastic deformation between the bolt and at least one of the first sub-assembly and the second sub-assembly.
