A clothing drying machine comprising:

• a casing that defines an exterior;
• a drum provided in the casing to receive clothing, the drum being rotatable about a substantially horizontal axis;
• a rear supporter that rotatably supports a rear side of the drum;
• a flow passage forming body including a flow passage that guides water introduced through an inlet to an outlet, the flow passage forming body being fixed to the rear supporter at an outside of the drum;
• a steam generating heater that applies heat to water flowing along the flow passage, the steam generating heater applying heat throughout the flow passage;
• and
• a nozzle that sprays steam generated by the steam generating heater, wherein the nozzle is fixedly coupled to the outlet to position the nozzle according to a fixed location of the flow passage forming body,
• wherein the inlet of the flow passage forming body is provided at a higher level than the nozzle so that when water is supplied through the inlet, gravity causes the supplied water to be discharged through the nozzle.
