The present invention relates to a buoyancy modulation globe. In order to make buoyancy modulation of a sinker convenient, and make connection and disassembly of the sinker to/from a hook (4) for minute modulation, when a hanger loop (1) is installed in a modulation member (3), a hanger loop groove (2) is established in the hanger loop (1) to buoyancy modulation of the sinker, the hanger loop groove (2) of the hanger loop (1) is used to connect the modulation member (3) to the hook (4) of the sinker so that the buoyancy is modulated. When the modulation is completed, in order to disassemble the modulation member (3) form the hook (4) and connect an insertion sinker to the modulation member (3), the hanger loop (1) is installed to the modulation member (3), and hanger loop groove (2) is established in the hanger loop (1). In addition, in the buoyancy modulation globe of the present invention, the hanger loop (1) of the modulation member (3) is wound to a fishing line so that the modulation member (3) is used as a movable sinker.COPYRIGHT KIPO 2018봉돌의 부력 조절을 편리하게 하고 미세한 조종이 가능하도록 봉돌의 (4)고리에 결합과 분해가 쉽도록 (3)조절부재에 (1)걸고리를 설치하고 (1)걸고리에 (2)걸고리홈을 개설하여, 봉돌의 부력조절을 할 때 (1)걸고리의 (2)걸고리홈을 이용하여 봉돌의 (4)고리에 (3)조절부재를 결합하여 부력을 조종하고 조종이 완료되면 (3)조절부재를 (4)고리에서 분해하여 (3)조절부재를 봉돌에 삽입 봉돌을 결합하여 사용하도록, (3)조절부재에 (1)걸고리가 설치되고 (1)걸고리에 (2)걸고리홈이 개설된 것을 특징으로 하는 부력조절구또한, (3)조절부재의 (1)걸고리를 낚싯줄에 감아 (3)조절부재를 유동 봉돌로 사용하는 것을 특징으로 하는 부력조절구
