    Abstract: Provided are a steel cord for reinforcing rubber whose fatigue resistance is increased more than ever to enable achieving high durability that was not conventionally realized, and a pneumatic radial tire including the steel cord as a reinforcement member.In a steel cord for reinforcing rubber having a double-twist structure that includes a plurality of strands twisted together in the same direction with the same pitch and including a central structure and at least one outer layer, the central structure is composed of at least two strands being twisted around each other and each being composed of at least seven filaments being twisted together. In a steel cord for reinforcing rubber including at least three core strands being twisted together and at least six sheath strands being twisted together around the core strands, the core strands and the sheath strands are twisted in the same direction.

    Abstract: A steel cord (10) comprises eight or more strands (12, 14) twisted together. Each of the strands has a substantially same cord twisting direction and a substantially same cord twisting pitch in the steel cord, and each of the strands consists of two to five individual filaments (16, 18) twisted together. Such a multi-strand steel cord can be manufactured without having to twist the individual strands separately and beforehand.

    Abstract: A metal cord having a core comprising one or more filaments for the reinforcement of rubber articles comprising a plurality of bundles of grouped filaments wherein the direction of lay of the filaments in the bundles is the same as the direction of lay of the bundles in the cord, each of the filaments having been subjected to plastic torsional deformation, and the average length of lay of each bundle in the cord being substantially equal to the average length of lay of each filament in the bundles, and wherein at any cross-section of the cord the filament or filaments which comprise the core of the cord differ along the length of the cord and belong to the same or different bundles.
