PURPOSE: To locate a washing nozzle accurately in place with respect to a washing trough by furnishing a locational part which locates a water guide path relative to the discharge hole of a washing pump, and fixing a nozzle bearing to the pump discharge hole.
CONSTITUTION: In the locational part 17 of a nozzle bearing, a projection 17-a and a hole 17-b are furnished which are detained with the discharge hole 12 of a washing pump and a water guide path 16. Detaining of these parts determines the positions and angles of the nozzle bearing locational part 17 and the water guide path 16 relative to the discharge hole 12 of the washing pump. Because mounted at the tip of the water guide path 16, a washing nozzle 7 is also located relative to the discharge hole 12 of the washing pump. This leads to locating the washing nozzle 7 relative to the washing pump 6 installed for the washing trough 2, so that the positioning of the washing nozzle 7 for the trough 2 is decided.
