Claims

[Scope of Claim for Utility Model Registration] An eccentric rotary cylinder whose outer circumferential center point and inner hole center point are eccentrically arranged between a cylindrical casing and a nozzle main shaft is rotatable via a rotary support member. An ultra-high pressure water cleaning nozzle that rotates and oscillates a nozzle hole with the eccentricity as a oscillation radius by interposing the nozzle hole, the guide cylindrical shape being integrally provided adjacent to the cylindrical casing. A guiding eccentric rotary cylinder having the same eccentricity as the eccentric rotating cylinder is rotatably provided in the casing via a rotation support member, and a guiding main shaft is rotatably supported in the eccentric inner hole of the guiding eccentric rotary cylinder. An ultra-high pressure water cleaning nozzle, characterized in that it is rotatably provided via a member, and the nozzle main shaft and the guide main shaft are integrally connected by an interlocking arm.
