In this invention, a ceramic nozzle is inserted into the fountain hole of a snow melting nozzle that communicates the outside with a cavity that communicates with the water pipe, and high-pressure fluid is spouted from this nozzle, thereby reducing the pressure inside the cavity of the snow melting nozzle. The inside of the snow removal nozzle can be easily cleaned by increasing the temperature and blowing away sand and pebbles that cause blockages. Furthermore, since the nozzle is made of ceramic, it can withstand high pressure and there is no risk of damage when inserted into the water fountain of the snow melting nozzle. Therefore, compared to the prior art, the inside of the snow removal nozzle can be cleaned reliably and quickly from every corner without removing the lid of the snow removal nozzle.
