    Abstract: PROBLEM TO BE SOLVED: To provide a steel cord useful for reinforcing a tire crown part in particular, producible in high efficiency with stable quality without any problems on its production as seen in conventional cases, and to provide a rubber-steel cord composite body and a tire each using the steel cord.
    SOLUTION: The steel cord has such a multilaid structure that N strands 2 (N=2-8) each with nearly elliptical crosssection made by laying a plurality of wires 1 are laid together. In the steel cord, the ratio d1/d2 is greater than 1.08 (wherein, d1 and d2 are the major axis and the minor axis of the strand 2, respectively). The steel cord meets the requirement:ε
    c >0.005, wherein ε
    c is defined by the following formula:ε
    c =√(-b/2+√(b
    2 /4-c))-1 [wherein b is -1+π
    2 (-4R
    2 +d

    2 d
    2 k(4π
    2 R

    2 )/P
    4 ; R is (D-d)/2; k is tan
    2 (π/2-π/N); and d is (d1+d2)/2; wherein D is the circumscribed circle diameter (mm) of the cord, and P is the twisting pitch (mm) of the cord].

    Abstract: PROBLEM TO BE SOLVED: To provide a steel cord which is a zero-degree belt cord following to the expansion in the radial direction of a tire in a vulcanizing treatment, reducing the elongation after molding of the tire, suppressing the expansion of the tire in the diametral direction during running and having low rigidity in the rotative direction of the tire and high rigidity in the direction intersecting the rotative direction of the tire at right angles.
    SOLUTION: The steel cord 1 has a 3×3 structure. The external tangent line S2 of strands 2 is a nearly elliptical shape in nearly the same direction in the longitudinal direction and the external tangent line S1 of the steel cord 1 is a nearly elliptical shape in the same direction as the elliptical direction of the strands 2. Furthermore, the strands 2 have an elliptical spiral preform (shown by dotted lines) with a smaller pitch than the lay pitch length of the steel cord and the contact or approach and separation of the adjacent strands 2 and 2 are present at least once in the one lay pitch.
