    Abstract: core strands comprising strands (A); and strands (B) disposed on the periphery of the core strands. In the core strands, the strands (A) have been upper-twisted and each strand (A) is composed of reinforcing fibers (A) and has been first-twisted. The strands (B) each is composed of reinforcing fibers (B) and has been first-twisted. The strands (B) have been upper-twisted and are disposed around the core strands. The direction of the upper twisting of the strands (B) is the same as the direction of the first twisting of at least one strand (B) selected among the strands (B). The number of first twists of the strands (B) is larger than the number of first twists of that strand (B) and/or the number of upper twists of the strands (B) is larger than the number of upper twists of that strand (B).

    Abstract: A steel cord (10) for the reinforcement of timing belts or transmission belts comprises only two to five strands (12) tightly twisted with each other in a first direction at a cord twisting pitch. Each of said strands (12) comprises only two to seven steel filaments (14) tightly twisted with each other in this first direction at a strand twisting pitch. The steel filaments (14) have a diameter ranging from 0.03 to 0.40 mm. The ratio strand twisting pitch to filament diameter is greater than 30, the ratio cord twisting pitch to filament diameter is greater than 30, and the ratio cord twisting pitch to strand twisting pitch is greater than 1. Such a steel cord has an acceptable low torsion moment under axial loads.

    Abstract: PROBLEM TO BE SOLVED: To provide a steel cord for reinforcement of a rubber product that improves the cord strength by preventing the occurrence of advance breaking of the outermost layer filaments of the steel cord having a multi-twisted structure, and a pneumatic tire which uses the same as a reinforcing material. SOLUTION: The steel cord for reinforcement of the rubber product has the multi-twisted structure formed by twisting multiple strands having a layer-twisted structure of multiple twisted steel filaments, with the ratio dc/ds of the diameter dc of outermost layer sheath filaments which form the outermost layer sheath of the core strands and the diameter ds of outermost layer sheath filaments which form the outermost layer sheath of the sheath strands being 1.05-1.25.
