<P>PROBLEM TO BE SOLVED: To provide a filling nozzle capable of excellently sealing a space between a nozzle and a folder, easily attachable/detachable, and capable of fixing a mesh without using any fixing tool such as a spring. <P>SOLUTION: The filling nozzle of a fixed-amount liquid filling device for filling liquid of the fixed amount in a container which includes meshes 41a, b, c of plate form arranged at a discharge port for discharging liquid from a nozzle body, and a nozzle fore end 14 which accommodates and fixes the meshes 41a, b, c, and is attachably/detachably mounted on a lower end of the nozzle body. The nozzle fore end 14 includes an upper opening for accommodating a lower end of the nozzle body, an engagement groove for engaging the nozzle body by a bayonet, a discharge port formed in the lower end, and an engaging stage 14a for preventing fall of the mesh. The meshes 41a, b, c are raised upwardly at peripheral edges 50a, b, c, and embedded in elastic seals 45a, b, c, and expanded as outer peripheral end faces 45A, B, C before mounting the meshes are located higher. <P>COPYRIGHT: (C)2012,JPO&INPIT |
