The spiral hose are used almost all automobiles as a reduction device of noise and vibration of the power steering system. The reduction mechanism of the spiral hose, however, has not been proved yet, therefore, efficient design method is not framed. Then, the hypotheses of reduction mechanism of spiral hose are formulated and verified experimentally. The hypotheses are the expansion-contraction effect of rubber hose, the resonance effect of insert type resonance tube and the resonance effect of hose branch type resonance tube. As the experimental setup, the power steering system for passenger cars installed on the test stand was used. The revolution tracking analyses of pressure fluctuation levels of rubber hose, insert type resonance tube and branch type resonance tube were performed. It were found that the reduction mechanism of spiral hose were the expansion-contraction effect of rubber hose and the resonance effect of hose branch type resonance tube.
