Abstract
A vibration absorbing hose has a corrugated portion extending substantially entire part of the hose and end portions of straight cylindrical shape. The vibration absorbing hose has multi-layered construction of tubular inner rubber layer, pressure resistant reinforcement layer circumscribing an outer side of the inner rubber layer and outer rubber layer as outermost cover layer. The pressure resistant reinforcement layer is formed, for example, by braiding reinforcing yarns, so as to have corrugations along the corrugated portion of the inner rubber layer.
