ABSTRACT:
A vibration absorbing hose including a corrugated portion 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 providing reinforcing yarns, so as to have corrugations along the corrugated portion of the inner rubber layer. The inner rubber layer contains scaly filler in an amount of 50 phr to 200 phr so as to be oriented in a stretching direction of the inner rubber layer. The scaly filler has an aspect ratio of 2 to 90.
