PROBLEM TO BE SOLVED: To provide a filling nozzle which can be attached and detached easily for cleaning or maintenance control and can fix a perforated plate (mesh) sufficiently. SOLUTION: In the filling nozzle, a nozzle tip 14 has an upper opening 43, in which the lower end of a nozzle body is stored, an engagement groove 42 being engaged in the nozzle body with a bayonet, an outlet formed at the lower end, an engaging step to prevent a mesh 44 from dropping from the outlet and a fixed spring to fix the mesh and assure engagement to the nozzle body, wherein the fixed spring has dimensions capable of passing through the upper opening and the stored spring is deformed to apply restoring force of the spring to the periphery of the mesh downward and outward to fix the mesh.
