Abstract: The hose of the present invention comprises a soft hose wall (A) and aspiral reinforcement (B) for retaining the configuration of the hose. Thehose wall (A) is formed with a composition comprised of: a resin component(A1) containing a diene-series or hydrogenated diene-series rubbercomponent, and an olefinic resin; and a lubricant (A2). The rubbercomponent may be a random or block copolymer of styrene and butadiene. Theolefinic resin may be a polypropylene-series resin. The lubricant (A2) maybe a higher fatty acid or its derivative (e.g., a higher fatty acidamide), a higher alcohol or its derivative, a hydrocarbon-series wax, anorganopolysiloxane, or fluorine-containing resin. The present inventionprovides a hose which is lighter, free from PVC, and capable ofmaintaining excellent flexibility even used for a long period of time.
