PROBLEM TO BE SOLVED: To provide a washing device which can wash the internal and external sections of the filling nozzle of a filling machine in a short period of time, and at the same time, drain a washing water without leaving the washing water remain in a washing water long cylinder, and surely perform a wash-sterilization. SOLUTION: This washing device for a filling nozzle comprises a pair of right and left washing water long cylinders 4 and 6, of which the top and the bottom sections are open, a thin tube 7 which connects the lower opening 5 of one side washing water long cylinder 4 and a specified location on the lower half section of the other side washing water long cylinder 6, and a communicating tube 9 which communicates the upper opening 8 of the other side washing water long cylinder 6 with a specified location of the upper half section of the one side washing water long cylinder 4. In this case, the inner diameter of the thin tube 7 is set to be smaller than at least the pair of the washing water long cylinders 4 and 6. The upper opening 3 of the one side washing water long cylinder 4 is formed as a closely joining fitting hole of the filling nozzle 2. At the same time, a water draining pipe 11 is fitted in the lower opening 10 of the other side washing water long cylinder 6. By this constitution, the washing water is made to flow down in the filling nozzle by an opening/closing operation of the filling nozzle 2, and after a wash-sterilization is performed, one section of the washing water is spirally raised and reversed in the one side washing water long cylinder 4, and thus, the outside of the filling nozzle 2 is wash-sterilized.
