A frictional vibration damper (10) for washing machines is disclosed. The damper comprises a piston body (24) and a piston rod (15) which adapted to move along the primary axis of said piston body (24). A friction element (19) is located in between the piston rod (15) and the piston body (24). The piston rod (15) and piston body (24) is equipped with joint (20) at one of their ends for connection to the frame and the drum of the washing machine. The piston rod (15) comprises a tubular body (16) which is made of sheet material and which is fixedly rolled around a carrier piece (14). The frictional damper (10) according to the present invention preferentially comprises, on one or both sides of the tubular body (16), with connection elements (26) in the longitudinal direction for engaging to corresponding connection elements (17) located on the carrier piece (14). |
