[Means for Solving the Problems]

 This invention has been proposed in order to achieve the above-mentioned object, and a float made of foamed styrol or the like is covered with a jacket made of polyester tarpaulin to form a float. For a float in a pollution control device that is made of polyester tarpaulin or the like at the end and has a cylindrical end cap with one side open, and for a joint that is made of polyester or the like at the open end of the end cap. The belt is attached, and the joint belt is attached to the outer cover while facing the joint belt, and a large number of small holes are formed in both joint belts in the circumferential direction. It is intended to provide a float for a pollution control device in which small holes are bound with a rope made of polypropylene or the like.

[0010]

[Action]

 The float floating on the surface of the water is capped by an end cap when the seawater is subjected to the rough waves of seawater, and the end cap and the outer cover are attached to the end side of the outer cover. Since the ropes are tied between the joint belts that are sewn into each of the joint belts through the holes formed in the joint belts, the end caps have sufficient stress against the large impact force of the rough waves. Is given. Thus, what is contained in the end cap is not subjected to rough waves, and is protected by the large response of the end cap, so that the end of the float is destroyed by rough waves. There is nothing that can be done, and the function of the float can be maintained for a long time.
