PURPOSE: A structure of a floating type is provided to inject or discharge air of a buoyance from an air pump by measuring force-causing movement of the structure. CONSTITUTION: A normal buoyance body receives buoyance force by injecting air from a lower portion thereof. The other buoyance body has an air hole on an upper end thereof to control the buoyance according to change of height of an end of a tube. The buoyance force bodies are assembled to form a buoyance assembly to form a floating structure. The structure is safely maintained by dispersing or offsetting waterpower of waves. The buoyance comprises plastic drum or a PVC pipe to make the floating structure to safe in an accident. Moreover, the floating structure conveniently controls the buoyance force according to the height of the tube and improves adaptability.
