PROBLEM TO BE SOLVED: To provide a flexible tube capable of setting a bellows tube to be displaced in an allowable range without depending on a metal meshed massive body or a blade cylindrical member for the bellows tube, while maintaining durability and reliability. SOLUTION: This flexible tube comprises a first tube 1, a second tube 3, the bellows tube 6, a first stopper 14 provided in the first tube 1, and a second stopper 34 provided in the second tube 3, so as to face the first stopper 14. The first stopper 14 has a first circular outer face 15, protruding toward the second stopper 34 in a circular form. The second stopper 34 has a second circular outer face 35, protruding toward the first stopper 14 in a circular form, where it faces the first stopper 14. The first circular outer face 15 and the second circular outer face 35 has less friction resistance, allowing smooth operation of the first stopper 14 and the second stopper 4.
