PROBLEM TO BE SOLVED: To provide a buoyancy applying tool which improves a performance of fitted to the body and moving performance and is miniaturized in being stored. SOLUTION: This buoyancy applying tool is so constituted that inflatable bags 12a, 12b, 12c are loaded in a jacket and a buoyancy material which is inflatable and holds the air in its inside is loaded in the inflatable bags 12a, 12b, 12c. The inflatable bags 12a, 12b, 12c are inflated along with the buoyancy material 13 by feeding a prescribed quantity of air from an air feed/exhaust part. 14 to the inflatable bags 12a, 12b, 12c so that the buoyancy applying tool 10 becomes to be fitted to the shape of the body and superior in moving performance, and when the buoyancy applying tool 10 is contracted, the inflatable bags 12a, 12b, 12c, and the air in the buoyancy material 13 are exhausted from the air feed/exhaust part 14 so that the inflatable bags 12a, 12b, 12c and the buoyancy material can be folded into small and prevented from being bulky so as to be stored compactly. |
