Abstract:
A cord for rubber reinforcement of the present invention includes a core strand including a plurality of strands (A), and a plurality of strands (B) disposed around the core strand. In the core strand, the plurality of strands (A) are finally twisted, and each of the plurality of strands (A) is formed of a plurality of reinforcing fibers (A) that are primarily twisted. Each of the plurality of strands (B) is formed of a plurality of reinforcing fibers (B) that are primarily twisted, and the plurality of strands (B) are finally twisted to be disposed around the core strand. The direction of final twist of the plurality of strands (B) is the same as the direction of primary twist in at least one strand (B) selected from the plurality of strands (B). The number of primary twists in the strand (B) is greater than the number of primary twists in the strand (A), and/or the number of final twists of the strands (B) is greater than the number of final twists of the strands (A).
