PROBLEM TO BE SOLVED: To provide an injection nozzle mechanism in which injection object spray patterns which are each independent clearly are formed, the injection nozzle mechanism including a center injection hole from which the injection is conical, and outer injection holes provided around the center injection hole.SOLUTION: A nozzle 14 includes an injection nozzle mechanism comprised of a center injection hole 18 which is opened forward, and two outer injection holes 19 which are opened vertically (outside of a radial direction) with respect to a center axis of the nozzle 14. A vertical wall 25 is formed on a side face of a nozzle chip 20 of the nozzle 14, and a distal end face 22a of a nozzle body 16 in the nozzle 14 is inclined to be spread toward a proximal end side. |
