Abstract: PROBLEM TO BE SOLVED: To simultaneously provide rust resistance and edge-separation resistance of a belt layer serving as a tension-resistant layer, by providing two steel element lines of a core with two-dimensional waving structure represented by a specific equation and specifying an oblate ratio of a steel cord.
SOLUTION: Two steel element lines f1 of a core fA are arranged right and left in parallel, and respectively have waving structures formed in two-dimensional wave shapes upwards and downward. The waving height H, the waving pitch L, and the diameter (d) of the steel element lines f1 satisfy the relation ship represented by the equations: 1.2≤H/d≤1.9, 8≤L/d, H/d≥0.048 L/d+0.536. A steel cord (f) is formed in a flat structure whose longitudinal axis is in the belt width direction, and an oblate ratio, represented by long diameter/short diameter, is set in the range of 1.05-1.25. Thus, while a strength of the steel cord (f) is kept, rubber can be satisfactorily permeate up to the inside of the core fA of the steel cord (f). Therefore, rust resistance can be greatly improved.
