（発明が解決しようとする問題点）
ここで問題となるのは、前記ノズルに超高圧水を供給す
る高圧給水ホースがノズルとともに動くことである。(Problems to be Solved by the Invention) The problem here is that the high-pressure water supply hose that supplies ultra-high pressure water to the nozzle moves together with the nozzle.

射装置で扱われる水圧は１０００に９／ａＡ以上もの超
高圧であるから、前記疲労によってホース接続部分の材
料が劣化すると前記超高圧によってその疲労部分が突然
破損する危険性もある。The connection part of this high-pressure water supply hose is susceptible to fatigue due to vibrations along with the nozzle, so if the eccentricity of the nozzle is small, this will not cause much of a problem. If this is increased, the movement of the connecting portion of the high-pressure water supply hose will also increase, and there is a risk that the hose connecting portion will be easily damaged due to fatigue. In particular, the water pressure handled by this type of ultra-high pressure water injection device is an ultra-high pressure of more than 9/1000/aA, so if the material of the hose connection part deteriorates due to the fatigue, the fatigue part will suddenly break due to the ultra-high pressure. There are also risks.
また、ノズルを直接的に偏心回転するので、ノズルは決
められた径で円運動を行うのみであり、ノズルの運動径

とができない。Furthermore, since the nozzle is directly eccentrically rotated, the nozzle only performs circular motion with a predetermined diameter, and it is not possible to adjust the nozzle's motion radius or move the nozzle along a motion locus other than circular motion.
以上の問題点は、回転駆動軸に対しノズルを傾斜状に設

で動かすことができるようにすることにある。The purpose of the present invention is to make it possible to reduce the movement of the connection part of a high-pressure water supply hose even when the movement of the nozzle is increased, to reduce fatigue of the connection part of the hose, and to adjust the movement diameter of the nozzle and to adjust the nozzle movement. The purpose is to enable movement with a trajectory other than circular motion.

軌跡で動かされる。Since the high-pressure water supply hose 22 is connected to the water guide shaft 11 at a portion closer to the universal bearing fulcrum 13 than the nozzle 12 or at the universal bearing fulcrum 13, the high-pressure water supply hose 22 can be connected even when the nozzle 12 moves largely. The movement of the parts becomes smaller. Further, the radius of motion of the nozzle 12 can be adjusted simply by changing the radius of motion of the actuating portion 14, and when the actuating portion 14 is driven into an arbitrary shape, the nozzle 12 is moved along a locus of motion other than circular motion.
