A flexible hose is provided to reduce the repair cost of pipe facilities, and to improve transporting ability of the pipe facilities by mounting a vibrator at a bent part of the hose. A flexible hose(100) includes an interlock tube(13), a bellows(12), and a vibrator(50). The interlock tube forms a pipe line(15) for flowing raw material particles with a fluid. The bellows is arranged by being separated from an outer circumference of the interlock tube by a predetermined distance. The vibrator is installed at a bent part of the hose, and converts electric energy to supersonic energy to provide the supersonic energy to the bellows. The vibrator is installed at a start point of the bent part. The flexible hose has a shape of "S", and has pipes(11) connected to both ends.
