A piston-cylinder mechanism comprises a tube (1) of cylindrical basic shape and two gable pieces arranged for its closure, of which pieces a first one (2) has an axial through-bore (15) for a rod (5) and a piston (4), the cylinder tube being made by cold forming of a tube-shaped blank of metal. According to the invention, said gable piece (2) is made in one piece with the cylinder tube (1) per se, the through-bore being delimited by a generally cylindrical surface in which is/are recessed one or several ring-shaped grooves (17, 18, 19) for the accommodation of a corresponding number of sealing rings (20, 21, 22). |
