Abstract

A vibration damper for a motor vehicle may comprise a damper outer tube, a damper inner tube having a lateral surface of the damper inner tube and arranged coaxially in the damper outer tube, a separating plate arranged coaxially in a region of the lateral surface of the damper inner tube, and a sealing element arranged coaxially circumferentially on the damper inner tube on the separating plate. In a region of the separating plate arranged coaxially on the lateral surface of the damper inner tube, a groove for the separating plate may be formed on the lateral surface of the damper inner tube. The separating plate may be arranged in the groove, and the connection between the groove and the separating plate may be press fit, at least in the radial direction.
