    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: The present invention provides structure of steel cord in heavy duty tires, in which the adhesive strength between filament and rubber, and penetrating property of rubber are improved by making the twist direction of core and strand different in the steel cord comprising core and strand filament, and by making the pitch or the twist period of core and strand different. In particular, this structure is applied to steel cord of 3+8*d(HT) which is used in heavy duty tires. In this application, twist direction of core filament is in the S direction and twist direction of strand filament is in the Z direction, and the ratio of the pitch of core filament (CP) and the pitch of strand filament (SP) is between 0.50 and 0.94.

    Abstract: The invention improves rubber permeability while making a cord diameter compact. A metal cord is constituted by a layered structure having a core comprising totally 6 to 12 filaments sectioned into 1 to 4 filament bundles, and a sheath comprising 8 to 15 filaments arranged around the core. Each of the filament bundles includes a waved filament modeled in a two-dimensional wave shape and a non-waved filament, in a state before being bundled. The core makes the wave of the waved filament three-dimensional within the core by applying torsion to each of the filament bundles.

    Abstract: A steel cord for reinforcing a high polymer material has a core formed by twisting three steel core filaments having a mutually equal diameter of 0.1 to 0.35 mm, and at least one sheath formed by twisting a plurality of steel sheath filaments having a mutually equal diameter of 0.1 to 0.35 mm and arranged around the core. The three core filaments are composed of one or two waving steel filaments each having waved portions apart from a longitudinal center line thereof, and an unwaving steel filament as a remainder. The clearances (T) between the waving steel filament and the unwaving steel filament are in a range of 0.15 to 0.6 times the diameter of the steel core filament. A sum total (M) of a mean void (m) between adjoining steel sheath filaments in each sheath is in a range of 5 to 35% of a sum total (N) of a mean center distance (n) between adjoining steel sheath filaments in each sheath.
