Abstract
A shock absorber comprises a tube with a cavity therein and a piston rod extending through one end of the tube. At this end of the tube there is provided a gasket. Moreover, for guiding the piston rod, there are provided guiding rollers. These guiding rollers are distributed about the axis of the tube and engage the piston rod by a concave circumferential face, the curvature of which substantially corresponds to the curvature of the piston rod.
