Abstract

A vibration damper may include a damper cylinder, a guiding closure that is held in the damper cylinder by a first clamping element, a piston rod that is axially guided in the guiding closure, and a piston rod functional group that is connected to the piston rod and disposed in the damper cylinder. At least one second clamping element may be connected to an internal wall of the damper cylinder, and a holding element may be disposed in the damper cylinder. The second clamping element can be disposed between the guiding closure and the holding element, and the holding element can be disposed between the second clamping element and the piston rod functional group. Further, the internal diameter of the second clamping element at least in portions is smaller than the external diameter of the holding element.
