摘要： PROBLEM TO BE SOLVED: To provide a thin-walled pipe, a manufacturing method of the thin walled-pipe and a molding device of a folding back part of the thin-walled pipe whereby danger of hurting a hand in handling can be reduced, and manufacture can be facilitated.
SOLUTION: This thin-walled pipe 1 is constituted by a pipe body 2, and the folding back parts 3 formed on both ends of the pipe body 2 along the axial direction. The folding back part 3 is formed by shaping extended pieces 31 extended from the pipe body 2 to be a folding back piece protruding from an outer periphery of the pipe body 2 to the radial outside by a molding roller having a folding back molding groove, and then crushing a part of the protruded folding back piece to the pipe body part 2 side by a crushing device so as to form the folding back piece in a state of being abutted to the outer periphery of the pipe body 2.
