PURPOSE: An inputting device of a rodless piston is provided to equally supply liquefied material having a high viscosity by a stroke of a piston and a volume of a cylinder without a piston shaft. CONSTITUTION: An input device of a rodless piston fills liquefied material of cosmetics, a shampoo or a lines. The input device comprises an entrance and an exit by 3-way directional valve, a cylinder and a fine controlling screw. Moreover, the input device is mass-assembled thereby improving productivity. The input device of the rodless piston is suitable for a food or sanity product by conveniently releasing in cleaning. The input device of the rodless piston removes reduction of production caused by endurance, life span, or trouble of a machine while producing a liquefied product. Thereby, the input device reduces damage and improves wear resistance and corrosion resistance.
