<P>PROBLEM TO BE SOLVED: To effectively use the warm air of a commercially available warm air fan heater although conventionally a Kotatsu itself having no heat source is not provided, to minimize unnecessary projections within a Kotatsu to widen an inner space, to keep a temperature in the entire Kotatsu more comfortable by an air quantity control lever, and to more effectively use a living space by providing a structure capable of horizontally rotating and fixing a connection pipe and duct. Ž<P>SOLUTION: In this Kotatsu shown in the Fig.1, the warm air of a commercially available warm air heater is guided by a universal pipe (flexible duct etc.) and used as a heat source.
