PROBLEM TO BE SOLVED: To provide an extension structure and an extension method for a liquid chemical injector capable of dealing with the increase in the volume of a liquid chemical at a low cost. SOLUTION: Regarding the extension structure and the extension method, the liquid chemical injector 1 combinedly composed of a liquid chemical tank 6 comprising drain port parts 10a, 10b and injection apparatuses 14, 15, 20 for injecting the liquid chemical within the chemical tank on an object to be injected with the liquid chemical, and apparatuses 2a to 2e for extension each obtained by removing the injection apparatuses 14, 15, 20 from the liquid chemical injector 1 and composed of only the remaining liquid chemical tank 6 are provided, and the drain port part 10a of the liquid chemical tank 6 in the liquid chemical injector and the drain port part 10b of each liquid chemical tank 6 in the apparatuses 2a to 2d for extension are connected, and the respective liquid chemical tanks 6, 6 are connected. In this way, utilizing the liquid chemical injector 1 which has been already installed as it is, a large volume of the liquid chemical can be stored. COPYRIGHT: (C)2006,JPO&NCIPI
