According to the above-mentioned nozzle, the high-pressure water ejected from each ejection hole opening in the nozzle main body serves as both the buoyancy / propulsion force of the nozzle and the foreign matter removing action. Since the holes have the same diameter, the high-pressure water that is ejected is ejected with a uniform water pressure. As a result, this high-pressure water is propelled while removing deposits in the pipe, but it is extremely difficult to eject high-pressure water that can cut and crush even the solid matter protruding into the pipe. The foreign matter in the pipe that is removed by the nozzle is about the amount of deposits in the pipe, and for example, tree roots, rubber packing, mortar lumps, etc. protruding into the pipe can hardly be removed.
