<P>PROBLEM TO BE SOLVED: To provide a metallic flexible pipe which can secure the sealing performance and retaining of a flexible pipe and a rotating nipple by a configuration not requiring welding and having a small parts count. <P>SOLUTION: It is formed in the tip tapered thread part 43a which is larger than the inside diameter of the rotating nipple 5 and smaller than the tip root diameter of the male screw 52 of the perimeter face 5a, the rear face side 43c of this tip tapered thread part 43a counters to 5d of the tip face of the rotating nipple 5, the seal ring 10 is inserted between the root part 42a of the flexible pipe 4 in the area where is covered by the rotating nipple 5 and the inner circumference face 5b of the rotating nipple 5, and the alignment ring 20 is inserted between the more tip root part 42b than the root part 42a, in which the seal ring 10 is inserted, and the rear root part 42c and the inner circumference face 5b of the rotating nipple 5, For this reason, it can prevent that the flexible pipe 4 moves to the axial direction of L back, falls out from the rotating nipple 5 and comes out of it without using welding and other member. <P>COPYRIGHT: (C)2012,JPO&INPIT |
