摘要： A steel cord for a tire which increases a corrosion resistance and durability and improves the energy efficiency during curing of the tire and a radial tire using the same. This steel cord has an mnulln twist structure comprising a core containing m pieces of wires and a sheath containing n pieces of wires, in which a rubber compound or an elastomer compound is filled into a space between the core and the sheath. Otherwise, the steel cord has a 1nullN twist structure containing N pieces of wires, in which a rubber compound or an elastomer compound is filled into a space at a cord center surrounded by the N pieces of wires.

摘要： In order that spaces, including a space in the central portion, inside a steel cord used as a reinforcement by being embedded in a tire or the like are filled with an uncured rubber, the uncured rubber is coated on plural steel filaments 115 which are then stranded in case of a single layer steel cord, the uncured rubber is coated on all of plural core filaments 329 which are then stranded along with outer layer filaments 330 in the same direction at the same pitch in case of a 2-layer steel cord of 1 stranding process, and the uncured rubber is coated on all or 2 to 4 core filaments 218 or on at least one of 3 or 4 steel filaments 408, 408null to form a core strand and outer layer filaments 410, 410null are stranded therearound in case of 2-layer steel cord of 2 stranding process. Consequently, it is possible to exhibit satisfactory corrosion resistance and satisfactory fatigue resistance as a steel cord, shorten a curing time in tire component assembling or the like to attain energy saving and prolong the life of a steel cord itself and the life of a tire or the like using the same as a reinforcement. Further, production can be performed at low cost.
