と補正する。Figure 1 shows a longitudinal cross-sectional front view of a part of a conventional flexible pipe, and Figure 2 shows an enlarged view of section A in Figure 2A, showing the various parts of a conventional flexible pipe when a bending load is applied. The calculated and measured stress values are shown. Figure 3 shows a longitudinal sectional front view of a portion of the flexible pipe based on this invention. Figure 4 shows a fatigue characteristic diagram of the material. 1...Flexible pipe, 2...Short diameter part, 3.8
...Proximity part, 6...Long diameter part. Amendment: March 31, 1982: The brief description of the drawing is amended as follows. On page 3, line 14 of the specification, ``shows a cross-sectional front view, and the opening of the second drawing'' is changed to r[shows a front view. Figure 2 A shows a vertical cross-sectional front view of a part of the flexible pipe of this invention, and the opening in Figure 2 is ``-''.

ことを特徴とするフレキシブルパイプ。A flexible pipe in which long diameter parts and short diameter parts having the same radius of curvature are alternately connected to form a wave shape, and at least one of the parts near the long diameter part and the part near the short diameter part has a short radius of curvature. A flexible pipe characterized in that the curvature of the diameter part is set larger than that of a half body.
