<p>PROBLEM TO BE SOLVED: To provide an underwater float provided with automatic striking function which allows a user to adjust a reeling out length of a striking line as desired by the user by automatically taking up the line by just quickly pulling the line and then releasing it, being able to determine a balancing sinking rate according to various operation mode so as to keep up the flow of an ocean current.SOLUTION: The underwater float is composed of a taking up part including a housing formed with a hollow section, a take up roll formed into a circular form and housed in the hollow section, and a spiral spring which is arranged in the take up roll and whose inner end is fixed to the housing and outer end is fixed to the take up roll so as to induce a rotational restitutive force; and a striking line whose one end is connected to an outer circumference of a frame of the take up roll so as to be taken up or reeled out by the rotation of the take up part, and other end penetrates the housing and protrudes outward of the housing.</p> |
