A frictional damper, in particular for washing machines with spinning action, comprises a circular cylindrical housing and a tappet which is coaxially displaceable inside the housing and extends out of it with one end, the other end being provided with a friction piston. The friction piston has at least one friction coating made of an elastically resilient material and is provided with a grease chamber. In order to prevent a decrease of damping because of change from lubricated to dry friction, the grease storage chamber is provided within the friction piston and is connected with the at least one support segment by way of at least one grease channel.
