Summary:PROBLEM TO BE SOLVED: To provide a rubber composition for a hose inner tube, and a hydraulic hose having an inner tube composed of the rubber composition for this hose inner tube, superior in fatigue resistance, while maintaining oil resistance. SOLUTION: This rubber composition for the hose inner tube includes at least high cis-butadiene rubber and acrylonitrile butadiene rubber, and is characterized in that the nitrile content of the whole rubber composition for the hose inner tube is 25-35 wt.%. The hydraulic hose also has the rubber composition for this hose inner tube in the hose inner tube. COPYRIGHT: (C)2010,JPO&INPIT
