Abstract
A nozzle device has a nozzle holes for injecting sprays grouped into spray groups respectively in injection directions. The nozzle device has an injection axis extending through the center in the thickness direction thereof. The injection axis perpendicularly intersects with an imaginary plane, which is at a predetermined distance from the nozzle device. The nozzle holes respectively have passage axes from which imaginary lines are respectively extended. The imaginary plane and the imaginary lines therebetween have intersections respectively defining outer intersections and an inner intersection in at least one of the spray groups. Each of the nozzle holes is inclined at an inclination angle being determined in such a manner that: the outer intersections exist in a polygon or a circle, and the inner intersection exists inside the outer intersections.
