Abstract
Disclosed is a power steering hose, in which at least two reinforcing layers are inserted between inner and outer rubber layers as to sandwich an intermediate rubber layer. Twisted cords of organic fibers constitute the reinforcing layers. The twisted cords have an intermediate elongation at 0.85 cN/dtex of 2.2 to 5%, an elongation at break of 8 to 19%, and a number of twists of 5 to 30/10 cm, respectively.
