For example, in the tilting type connected by the center ring in FIG.
The shape of the opposing pressure receiving plates is spherical only on one side and flat on the other. However, the shape is not limited to this, and both pressure receiving plates can be spherical. Further, the form of attaching the connecting arm 3 of this type to the buoyant body F is welded to the sealing partition plate 1a as shown in FIG. 1, but is not necessarily limited to this, as shown in the right part of FIG. Then, a brim-shaped circular plate 10a 'for attachment is welded to the right end of the connecting arm, an annular attachment plate 1d is welded to the steel pipe 1 in advance, and both vault holes are aligned and fixed with a vault nut 14'. It is also possible.

6, the annular mounting plate 1d is welded to the steel pipe 1 in advance, and both are fixed with the vault nut 14. However, the method is not necessarily limited to this, and as shown in the right part of FIG. Furthermore, it is also possible to weld to the partition plate 1a to be hermetically sealed.

【発明の効果】本発明の筒状浮力体の連結構造は、以上
のように構成されているため、傾動回転を円滑に行うこ
とができ、かつ衝撃緩和に連結することができる。As described above, the connecting structure of the tubular buoyant body of the present invention is constructed as described above, so that the tilting rotation can be performed smoothly and the connection can be made to reduce the impact.

供することができる。On the other hand, if attention is paid to the service life, the torsional force does not act on the connecting portion due to the rotating device or the contact form between the tires, so that damage to the connecting portion can be kept to a minimum. Therefore, the service life can be greatly increased. Therefore, an economically excellent connection structure can be provided.
【００４２】連結部の損傷が軽微に改善され、経済性も

廃棄タイヤの有効利用に大きく寄与するものとなる。In connection with the fact that the damage of the connecting portion is slightly improved and the economic efficiency is improved, the demand for a buoyant body in which the outer periphery of the steel pipe base is covered with old tires increases. This greatly contributes to the effective use of discarded tires.
