摘要： Provided are a piping cleaning nozzle which effectively prevents back flow of a cleaning agent poured into piping in a building to clean the inner wall of the piping and to exterminate noxious organisms, and a piping cleaning method using the piping cleaning nozzle. An expanding and contracting body (4) is mounted to the front end side of a pipe (3) constituting a nozzle inserted into piping. The expanding and contracting body (4) is adapted to cover nozzle holes (8) for discharging a cleaning agent and consists of a material such a rubber expanded by the cleaning agent discharged to the inside of the expanding and contracting body (4). In cleaning operation, the pressure of the cleaning agent discharged from the nozzle holes (8) expands the expanding and contracting body (4) to close the piping. As a result, the expanding and contracting body (4) functions as a lid for blocking the cleaning agent which comes out of a discharge opening (6) and tried to flow back. This causes the cleaning agent to be effectively prevented from flowing back and to be sent to a portion deep inside the piping, enhancing cleaning efficiency.
