PURPOSE: A flexible tube for absorbing large displacement vibration is provided to mount additional springs outside an outer blade for absorbing the vibration of a large scale beyond the vibration absorption limit of a bellows. CONSTITUTION: A flexible tube for absorbing large displacement vibration includes a stopper(25), a spring supporting plate(27) and a plurality of springs(30). The stopper is provided to an outer peripheral surface of a cap(23) at an emission introducing part for a bellows(22). The stopper is formed of a plate having a larger area than an outer diameter of an outer blade(21), and a through hole(26) is formed in the center of the plate with an inner diameter larger than an outer diameter of the cap. The spring supporting plate is fixed to an emission discharge part and has an area larger than the outer diameter of the outer blade. The springs are mounted between the stopper and the spring supporting plate.
