ABSTRACT:
A rubber product-reinforcing metallic cord is provided which comprises three to five metallic filaments, which shows a high degree of penetration of rubber without reducing compressive rigidity, and which can be manufactured at low facility and production costs. A rubber product-reinforcing metallic cord7is formed by twisting together a pre-strand6comprising a first metallic filament1and a second metallic filament2helically wrapped around the first filament1, and a fifth metallic filament3(or5) with a twist pitch P. The metallic cord7may be formed by twisting together two of such pre-strands, or by twisting together two of such pre-strands and the fifth metallic filament.
