PROBLEM TO BE SOLVED: To provide a dishwasher which ensures attaching and detaching of a nozzle assembly nut for a nozzle header.SOLUTION: In a dishwasher 1, threads 34 provided on a nozzle assembly nut 32 are formed intermittently in winding direction around a vertical axis L. Since an intermittent part S of the thread 34 is aligned in a vertical direction, when the nozzle assembly nut 32 is tightened to a nozzle header 31, cleaning scum W which enters a thread groove 42 of the nozzle header 31 is moved so that it is extruded by the threads 34 of the nozzle assembly nut 32. Then, the cleaning scum W is exhausted so that it falls from the intermittent part S of the threads 34. This configuration prevents the cleaning scum W from being caught. |
