Abstract

In a shock absorber unit for vehicles of the double-tube type a piston rod guiding member is provided at respective first ends of a cylinder and a container surrounding the cylinder. The first end of the container engagingly surrounds a radially outer face of the piston rod guide member. The container is tube-shaped and has substantially constant wall thickness along its total length. The radially outer surface of the piston rod guiding member is provided with at least one radially inward directed recess or at least one radially outward directed projection. The first end of the container is deformed such as to engage this projection or recess respectively. A sleeve member engagingly surrounds the first end of the container. This sleeve member is also provided with a deformation which deformation is in engagement with the deformation of the container.
