(See Figure 3 (B)) A plurality of floating bodies l are covered with waterproof covers 2, and then the waterproof covers 2 are glued by being pushed into the gaps of each floating body 1, and the waterproof covers 2 are The floating body 1 is bonded to be gripped by the waterproof cover 2 so that a portion of the floating body 1 forms a protrusion 4 that protrudes along its generatrix (see FIG. 4). Next, a series of flexible floating bodies formed in this way is inserted into a long cylindrical protective cover 3 (see FIG. 5(a)).
Alternatively, by covering the continuous body of the floating body with a rectangular protective cover 3 (see FIG. 5(b)), the floating body 1 is further covered with the protective cover 3 from above the waterproof cover 2. Thereafter, the protective cover 3 is deformed so that a protruding part 5 that protrudes along the protruding part 4 of the waterproof cover 2 is formed in a part of the protective cover 3 (see FIG. 6). Both of the protrusions 4.5 are integrally sewn or welded together with the reinforcing belts 6 that abut on both sides (see FIG. 7).
上述した製造方法により、本発明にかかる構造の浮力体

触が避けられ、浮体１の摩耗が少ない。As described above, in the buoyant body according to the present invention, the floating body 1 is covered (surrounded) by both the waterproof cover 2 and the protective cover 3.
Because of this, water-stop properties are effective, and the waterproof cover 2
Due to the presence of the floating body 1, direct contact between the floating body 1 and the strong protective cover 3 is avoided, and wear of the floating body 1 is reduced.

If a part of the waterproof cover 2 is made to protrude integrally along their generatrix lines, and those protruding parts 4 and 5 are integrally sewn or welded together with the reinforcing belt 6, a single piece formed by the waterproof cover 2 can be formed. A continuous body of a plurality of flexible floating bodies can be securely fixed within the protective cover 3, and the floating bodies themselves can also be made stronger.
