PURPOSE: A structure of a nozzle for chemistry fluid is provided to seal the space between a flange of the nozzle and a mouth of lining sleeve, thereby preventing fluid from leaking in the nozzle. CONSTITUTION: A body of a reservoir for chemistry fluid is formed with a cladding material(110), and a body of a nozzle(200) for supplying the fluid into a tank is formed with a lining sleeve(210). A base of the lining sleeve is welded to an inner lining(220) of the nozzle. An upper end of the lining sleeve is welded to a seat ring(230) mounted to a flange(250) and a back seat ring disposed under the seat ring. The seat ring is formed with a welding groove at an inner surface, and is welded to an end portion of the lining sleeve.
