摘要

PROBLEM TO BE SOLVED: To provide a rust removing device for water supply equipment suitable for removing a rust hump formed on the back side of a water supply pipe by inserting a cutting tool into the water supply pipe. SOLUTION: This water supply facility rust removing device 1 includes a fluid ejector 2 for ejecting a fluid from an outlet portion 2a, and a flexible pipe body 3 whose rear end portion is attached to the ejection port portion 2a to guide the fluid. The joint portion 4b has a joint portion 4b that rotatably connects the cutting portion 4a and the cutting portion 4a, and the joint portion 4b is the pipe body 3 so that the rotation axis direction of the cutting portion 4a coincides with the axial direction of the tip portion of the pipe body 3. A fluid path 40, which is attached to the tip of the pipe body 3 and injects a fluid from the pipe body 3 to bend the path of the fluid and ejects the fluid, is formed inside, and the cutting portion 4a rotates with respect to the joint portion 4b by ejecting the fluid.
