PROBLEM TO BE SOLVED: To provide a compact washing nozzle mounting device incorporated with an injection port switching mechanism which starts reciprocal rotation only by supplying washing water or the like so as to simply realize an efficient washing operation. SOLUTION: A rotation part 2, which moves reciprocally, is provided with a washing nozzle connection port C2 in a normal injecting direction F and a nozzle connection port D2 in a reverse injection direction R with an axial part 1 having a water supply port A fixed to a high pressure water pipe or the like and the axial part as a central axis. Rotation power generated by the injection of the washing nozzle is intermittently pressed from a pin 4 installed to the rotation part 2 to the notched part 3a or 3b of a switching part 3 to drive the switching part 3 in the rotating direction of the rotation part. Thereby, the flow of the washing water or the like from a water supply port A is alternately switched between through holes of the switching parts C1 and D1 through a distribution pipe B to repeat the injection normally or reversely in the injection direction of the rotation part 2.
