摘要：
A steel cord for reinforcing a rubber product has a multilayer structure consisting of two or more layers including a core, or a structure consisting of seven or more strands twisted in the same direction at the same pitch. In the steel cord, at least one of three strands that are successively adjacent to one another or that are in mutual contact is formed of two filaments that are paired substantially parallel to each other. The direction of pairing the two filaments of each strand is substantially the same over the entire length of the cord. Each of the remaining strands is formed of a single filament. The steel cord is utilized in elastomeric products such as pneumatic radial tires as a reinforcing material so as to increase their durability.
