The present invention relates to a dispensing nozzle unit, in which: a nozzle is manufactured in a miniature size; and an internal diameter portion of an assembling groove end of a guide for assembling the nozzle is improved such that a spray hole of the nozzle is positioned on the center when an adjusting nut is coupled and assembled, whereby a spraying operation is performed in an exact area through the nozzle when a corresponding fluid is supplied, thereby obtaining a high-precision processing effect, wherein the dispensing nozzle unit is formed as a conical shape in which: the internal diameter of an assembling groove end (32) for guiding a nozzle (40) is slantly formed in a shape that narrows towards an upper part; and the external diameter of said nozzle (40) is guided according to the slanted assembling groove end (32) such that a spray hole (41) of the nozzle (40) is exactly positioned on the center of an installation hole (11) when an adjusting nut (50) for a screw coupling portion (12) is coupled. |
