Claims (1)

[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. In an ultra-high pressure water cleaning nozzle in which the nozzle hole is rotated and oscillated by using the eccentric amount as the oscillation radius, the support protrudes substantially horizontally from one side of the nozzle having the nozzle hole; An ultra-high-pressure water introduction hole communicating with the nozzle hole is opened in the arm, and the downstream side of a flexible pressure-resistant hose is connected to the inflow hole side of the ultra-high-pressure water introduction hole, and a motor for rotating the eccentric rotating cylinder is connected to the eccentric An ultra-high pressure water cleaning nozzle characterized by being placed at the top of a rotating cylinder.
