PURPOSE:To prevent the abrasion and breakage of massive floats by connecting massive floats of expanded material with an air float with elbow pipes for supplying or discharging compressed air by an U-shaped elastic connecting plate. CONSTITUTION:A prevention film for diffusion muddling consists of an air float 1 with an elbow pipe 3 for supplying or discharging compressed air, a massive float 3 expanded material, etc., and a U-shaped connecting plate 10 of an adequate elasticity. A danger of collision of the float 2 with the metal of the pipe 3 can be avoided even when both the floats 1 and 2 are mutually moved by tidal waves because the plate 10 has adequate rigidity and cushioning property. Therefore, the abrasion and breakage of the float 2 can be prevented.
