PURPOSE: A water-jet blow assembly for facilitating the bind and preventing the twisting of a hose is provided to improve the performance productivity of a water jet by manufacturing a high pressure water inflow part using a mold. CONSTITUTION: A water-jet blow assembly comprises an converging part(10), a check valve and a nozzle(20). The inside of the converging part is formed in a streamlined shape in order to minimize the flowing force of the flowing water and reduce the pressure loss of the flowing water. A guide bar(51) of a check valve is guided to a guide pipe. The water flow rate is gradually increased by a pressurizing nozzle(30) and a high-pressure part(21).
