Abstract
A rubber product that includes a cylindrical molded body having a plurality of reinforcing layers coaxially layered between inner and outer layers. In producing/vulcanizing the molded body, a rubber product including a cylindrical portion, each of multiple reinforcing layers composed of cord fabrics including a large number of fiber cords aligned and subjected to a predetermined adhesion treatment and coating rubber layers covering both surfaces of the cord fabric, and a bias structure in which the fiber cords of the reinforcing layers extend in an intersecting direction is formed. Each of the cord fabrics has: a tensile strength of ≥4320 N/cm in a cord extension direction and a weight of ≤950 g/m, each of the cord fabrics has a bending hardness of ≤30 g/cm after the predetermined adhesion treatment, and each of the coating rubber layers has a layer thickness of ≥0.2 mm and ≤1 mm.
