To endure application over a long period of time.SOLUTION: A flotation adjustment device 10 includes: a cylinder 11; a piston 12 inserted in the cylinder 11 for partitioning inside of the cylinder 11 into a water chamber 23 and an air chamber 24; bellows 14 attached to the cylinder 11 as well as being arranged in the water chamber 23 for partitioning the water chamber 23 into a bellows inner chamber 27 and a bellows outer chamber 28; a first sealing unit 16 formed on cylinder inner periphery surface 11c and outer periphery surface 22c of the piston 12 for preventing movement of air and sea water from one to the other in the water chamber 23 and the air chamber 24; and a second sealing unit 17 provided in a connection unit between the cylinder 11 and the bellows 14. The bellows 14 increases and decreases capacity of the bellows inner chamber 27 for storing sea water for flotation amount adjustment according to movement of the piston 12.SELECTED DRAWING: Figure 2

    【課題】長期間の運用に耐える。【解決手段】浮量調整装置10は、シリンダ11と、シリンダ11に挿入されて、シリンダ11の内部を水室23と空気室24とに仕切るピストン12と、水室23に配置されると共にシリンダ11に取り付けられて、水室23をジャバラ内室27とジャバラ外室28とに仕切るジャバラ14と、シリンダ内周面11cとピストン12の外周面22cとに形成され、水室23及び空気室24において一方から他方への空気及び海水の移動を阻害する第1封止部16と、シリンダ11とジャバラ14との接続部に設けられた第2封止部17と、を備える。ジャバラ14は、ピストン12の移動に応じて、浮量調整のための海水を収容するジャバラ内室27の容積を増減させる。【選択図】図2
