PROBLEM TO BE SOLVED: To provide a rope-type underwater floating and sinking body that can easily float and sink underwater even in a state of being connected to a rope body.SOLUTION: A rope-type underwater floating and sinking body 1 that can easily float and sink underwater in a state of being connected to a rope body includes a body part 3 having a shape extending in a longitudinal direction, a wing part 4 disposed to the body part 3, and elevation angle adjustment means 5 disposed to the body part 3 for adjusting an elevation angle of the wing part 4. Using the elevation angle adjustment means 5, the elevation angle is adjusted at the time of floating so that lift force generated by the wing part 4 is greater than resistance force generated by the rope body, and the elevation angle is adjusted at the time of sinking so that lift force generated by the wing part 4 is smaller than resistance force generated by the rope body.SELECTED DRAWING: Figure 3
【課題】索体に接続された状態であっても容易に水中で浮沈可能な有索式水中浮沈体を提供する。【解決手段】索体に接続された状態で水中を浮沈可能な有索式水中浮沈体1であって、前後方向に延伸した形状を有する本体部3と、本体部3に配置された翼部4と、本体部3に配置され翼部4の迎角を調整する迎角調整手段5と、を備え、迎角調整手段5によって、浮上時には翼部4により発生する揚力が索体により発生する抗力よりも大きくなるように迎角を調整し、沈降時には翼部4により発生する揚力が索体により発生する抗力よりも小さくなるように迎角を調整するようにした。【選択図】図3
