Abstract

A piston-cylinder unit for shock absorbers or the like is formed with a tubular container surrounding the cylinder and with a piston rod guide and sealing unit mounted at one end of the container with a support for the cylinder at the other end of the container. In order to effect a satisfactory sealing action at the fixing points of the cylinder, the cylinder is formed with a radial indentation.
