Abstract
A vibration absorbing hose including a corrugated portion has multi-layered construction of tubular inner rubber layer, pressure resistant reinforcement layer formed on an outer side of the inner rubber layer by providing reinforcing yarns. A radial depth B of the pressure resistant reinforcement layer at a position of each of corrugation valleys of the rubber layer has such relationship with respect to a corrugation valley depth A of the rubber layer as 0< or =B< or =0.7×A, and an opening angle θ of each of the corrugation valleys of the rubber layer satisfies θ< or =100°.
