Abstract
A vibration damper may comprise a damper tube filled at least partially with damping liquid. A piston rod is movable to and fro in the damper tube, and a working piston is movable with the piston rod. The working piston may divide an interior space of the damper tube into a piston rod-side working space and a working space distal the piston rod. A piston rod attachment may include an attachment element, a bracing element, and a wedge element. On a side that faces away from the working piston, the piston rod may have a wedge element cut-out for partially receiving the wedge element in a braced state. The attachment element may be connected to the bracing element such that the attachment element braces the bracing element with respect to the piston rod via the wedge element arranged in the wedge element cut-out.
