PROBLEM TO BE SOLVED: To provide a tube form member structure capable of preventing unwinding of an end part of a flexible pipe formed by a band like member without increasing costs. SOLUTION: The flexible pipe 1 is formed by spirally winding up the metal band like member in an axial direction, and corrugated uneven parts 4 and 5 are continuously formed in the axial direction in a circumferential wall surface of the flexible pipe 1. Crushed parts 6 are formed on uneven parts 4 and 5 positioned in end parts of the cylindrical member to prevent unwinding of the band like member positioned in end parts 7 of the flexible pipe 1. |
