Zusammenfassung:	PROBLEM TO BE SOLVED: To uniformly jet pulverized fluid at a wide angle outside the periphery. SOLUTION: A nozzle tip 12 is housed in a nozzle main body 11 and a deflector 15 is provided to the tip side of the nozzle. For the nozzle tip 12, a spiral groove 12g is provided to a rear end surface 12d, and a nozzle hole 12k is projected to enlarge an inner diameter to the tip side. Then, for a deflector 15, a continuous position 15d of a supporting rod 15a to a collision plate part 15b is formed with a curved surface to be smoothly continued to a collision surface 15c. A spiral fluid T is jetted from the nozzle hole 12k, and deviated on the continuous position 15d to be jetted at a wide angle outward along the collision surface 15c. COPYRIGHT: (C)2003,JPO
