PROBLEM TO BE SOLVED: To process a snow-melting nozzle extremely easily, and to make it possible to finely change the injection of snow-melting water over the entire circumferential direction. SOLUTION: An upper part 1a formed of an inverted conical cavity 4 to which a sprinkler member 2 for ejecting snow-melting water is mounted, and a lower part 1b to which a water pipe 3 through which snow-melting water flows from underground is connected. It is a snow-melting nozzle 1 that has The sprinkler member 2 divides a disk into upper and lower parts to form a fountain plate 21 on the upper side and a support plate 23 on the lower side. The fountain plate 21 is provided with a convex portion 22 inclined downward toward the center, and the support plate 23 is provided. A recess 24 into which the convex portion 22 is fitted is provided, a through hole 29 through which a valve cylinder 10 mounted on the water guide pipe 3 is inserted is opened in the bottom surface 24a of the recess 24, and the peripheral edge of the through hole 29 is a corrugated circle. A locking pin 28 formed on the circumference 29a, having a plurality of snow-melting water fountain grooves 25 formed in the convex portion 22 in the radial direction and projecting downward to lock into the valley of the corrugated circumference 29a. To plant. [Selection diagram] Fig. 1
