Abstract: A sliding structure and a joint member, which are provided with a sliding means which substantially eliminates the so-called Stick-Slip effect. This is achieved through the provision of free ends of a plurality of projections, sliding upon the surface of a complementary opposed and facing surface. By appropriately dimensioning the individual free end contact surfaces of the projections and by selectively varying in the number of the projections per area unit, the difference between the initial still-stand holding effect and the sliding friction in the case of selected material pairings is considerably reduced. The force, which is necessary to set the two sliding components into motion, relative to one another, is then only insignificantly greater than the force necessary to overcome dynamic or sliding friction. The Stick-Slip effect is known and unavoidable in a case with a sliding pair of unfavorable materials and, in this manner, can be effectively reduced.
