ABSTRACT:
In a flexible pipe having shape retaining capabilities, a first pipe is provided having a first base wire and a first subsidiary wire, the first base wire being wound in a spiral manner, the first subsidiary wire externally covering the first base wire and being fit into an external valley of the first base wire, and a second pipe having a second base wire and a second subsidiary wire, the second base wire being wound in a spiral manner in an opposite direction from the first base wire, the second subsidiary wire externally covering the second base wire and being fit into an external valley of the second base wire. The second pipe being provided inside and in contact with the first pipe. When a torsional force is applied to the first pipe, the second pipe generates a bearing force against the torsional force.
