The invention relates to a vibration reduction device based on parallel mechanisms and special for an automobile steering wheel. The vibration reduction device comprises a main supporting rod. The two sides of the upper end of the main supporting rod are symmetrically provided with two limiting pieces. The middle of the main supporting rod is provided with an auxiliary supporting rod in a welded mode. The upper end of the main supporting rod is sleeved with a moving cylinder. A threaded hole is formed outside the moving cylinder. The threaded hole is provided with a limiting rotary knob. The two sides of the moving cylinder are symmetrically provided with two inclined rods in a welded mode. The upper end faces of the two inclined rods and the upper end face of the moving cylinder are provided with a mounting panel in a welded mode. The middle of the upper end face of the mounting panel is provided with a fixing shaft. The fixing shaft is connected with a rotating cylinder through a bearing. The upper end face of the rotating cylinder is welded to a vibration reduction supporting plate. The two sides of the upper end face of the vibration reduction supporting plate are symmetrically provided with the two parallel mechanisms. The upper end faces of the two parallel mechanisms are provided with a supporting panel. Three rows of vibration reduction springs are evenly arranged between the supporting panel and the vibration reduction supporting plate. By means of the vibration reduction device, vibration reduction and supporting functions of the automobile steering wheel can be achieved, and a driver can drive an automobile stably without feeling pain at the hands.
