    Abstract: A steel cord which is suitable for reinforcing a rubber product and has excellent fatigue resistance. The steel cord has a layer-twisted structure formed by steel filaments respectively having a diameter of 0.15 mm to 0.25 mm. A core of the steel cord is formed by 1 to 4 steel filaments. A least 6 steel filaments are wound around the steel filaments of the core to form at least one layer. When the steel cord is bent from a straight state to a state in which a radius of curvature thereof is d/(17.times.10.sup.-3) wherein d is a diameter in millimeters of each steel filament in an outermost layer of the steel cord, a maximum amount of movement of each steel filament in the outermost layer in a cross-section of the steel cord is less than or equal to (-0.5454d+0.1454).times.10.sup.3 um. The steel cord preferably has a two-layer-twisted structure or a three-layer-twisted structure, and has an arrangement in which the diameters of the steel filaments gradually decrease from the core to the outermost layer.

    Abstract: A steel cord effective for reinforcing a super-large off-road tire wherein strands made by simultaneously twisting together 3 to 6 steel wires in the same twisting direction with the same pitch length are used and the steel cord is made by twisting together 3 to 6 such strands in the same direction as the twisting direction of the strands and with the same pitch length. Each of the steel wires constituting the strands continuously has a small wavy pattern of a pitch length smaller than the lay length of the strands and therefore each of the strands has a compound pattern comprising a wavy pattern formed by the twisting and said small wavy pattern and in a gap is formed between steel wires each of the strands by the small wavy pattern. The lay length P.sub.1 of the steel cord is 8 to 15 times the steel cord diameter D and the elongation on breakage by tension of the steel cord is over 5%.
