Claims

[Scope of Claim for Utility Model Registration] Leakage at a joint of a fluid transport pipe that seals the outer periphery of a joint that connects two fluid transport pipes to prevent the diffusion of fluid leaking from the joint. The fluid diffusion prevention structure is such that the inner peripheral edge of each elastic member formed of a flexible material is closely fixed to the outer peripheral surface of the pipe end of each of the fluid transport pipes, and is disposed on the outer peripheral surface of the joint part. A leakage fluid diffusion prevention structure at a joint of a fluid transport pipe, in which the outer peripheral edge of each of the elastic members is tightly fixed to the inner peripheral surface of the end of the protective cover.
