PURPOSE: A steam temperature preservation apparatus for a steam cleaner is provided to improve cleaning efficiency by regulating pressure and temperature of steam discharged from an injection nozzle with mounting the temperature preservation apparatus in the discharge port of the pressure container. CONSTITUTION: A steam temperature preservation apparatus comprises a pressure container(1) storing water, injecting water to an injection port and opening and closing the injection port by a container lid; a heater installed in the pressure container to generate steam by heating water stored in the pressure container; an injection nozzle receiving stream from the pressure container and ejecting stream to clean pollutants; a connecting pipe(6) communicated with a discharge port(5) formed in the pressure container to discharge steam and composed of an opening valve and the injection nozzle; and a temperature keeping unit(10) installed in the discharge port of the pressure container to keep temperature of steam from the injection nozzle over the reference value.
