PROBLEM TO BE SOLVED: To provide a water movable body which inhibits leakage of a working fluid to the outside of a system and mixing of air into the system.SOLUTION: A water movable body 1 may come and go between water and a water surface and has a specific gravity adjustment part 2 having an air bladder 21 which may expand and contract, a pump unit 22 which supplies a liquid to the air bladder 21, and a liquid tank 23 which stores a working fluid supplied to the air bladder 21 through the pump unit 22. The pump unit 22 is immersed in the working fluid in the liquid tank 23. The liquid tank 23 is formed so that the capacity may vary according to an amount of the working fluid supplied to the air bladder 21.SELECTED DRAWING: Figure 1
【課題】系外への作動液の漏洩及び系内への空気の混入を抑制することができる、水中移動体を提供する。【解決手段】水中と水面との間を往来可能な水中移動体1であって、膨縮可能な浮袋21と、浮袋21に液体を供給するポンプユニット22と、ポンプユニット22を介して浮袋21に供給される作動液を貯留する液体タンク23と、を備えた比重調整部2を有し、ポンプユニット22は、液体タンク23内の作動液中に浸漬されており、液体タンク23は、浮袋21への作動液の供給量に応じて容量可変に構成されている。【選択図】図1
