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 cordis formed by twisting together a pre-strandcomprising a first metallic filamentand a second metallic filamenthelically wrapped around the first filament, and a fifth metallic filament(or) with a twist pitch P. The metallic cordmay be formed by twisting together two of such pre-strands, or by twisting together two of such pre-strands and the fifth metallic filament.
