PROBLEM TO BE SOLVED: To provide a snow melting nozzle with a ring member prevented from turning by stopper latches by providing the ring member and a nozzle main body with the stopper latches, wherein a spray direction can be changed easily. SOLUTION: A plurality of the stopper latches 3a comprising a pair of rising parts opposed to each other to sandwich the stopper latch 6a on the ring member 6 to be fitted in a fitting recessed groove 7 are provided on the nozzle body 3 in the circumferential direction. The distance between the opposing rising parts is approximately same as or wider than the width of one or a plurality of the stopper latches formed on the ring member. At least one of the stopper latches on the ring member can be fitted between the rising parts. The ring member can be freely turned within a determined range until the stopper latch on the ring member collides against the rising parts in the state of being fitted in the recessed groove 7 or the stopper latch is fitted between the other rising parts.
