Abstract: A twisted cable includes a main body which includes a central filament and a plurality of twisted filaments. The twisted filaments are arranged around the central filament and include six first filaments, twelve second filaments, and eighteen third filaments from the central filament outward. The cross-section of each first filament is the same with the one of each second filament. The cross-section of each first filament is larger than the one of the third filament but smaller than the one of the central filament. The twisted filaments are twisted around the central filament. As a result, the twisted cable of the present invention has improved structure strength, appropriate toughness, and smaller amount of longitudinal deformation.

Abstract: The object of this invention is to provide a steel cord, which has ultrafine steel filaments with a diameter of 0.04-0.14 mm stranded with each other so as to reinforce a tire carcass, and a radial tire for a passenger car using the same. The steel cord includes one core filament with a diameter of 0.04-0.14 mm and 4-7 sheath filaments, each having a diameter of 0.04-0.14 mm, spirally stranded around the core filament. At this time, the steel cord has a diameter of 0.2-0.5 mm and shear strength of 25-35 kgf. Additionally, each of the sheath filaments has a smaller diameter than the core filament, and the core filament and the sheath filaments are made of the steel filaments. The radial tire includes the tire carcass provided with the steel cord and a topping sheet, and the steel cord is embedded in the topping sheet such that a rubber gauge ratio is 200-500 % and a rubber clearance ratio is 60-250 %. The steel cord has improved physical properties, such as shear strength and durability, to reduce a thickness of a carcass including the steel cord, leading to the reduction of a weight of the radial tire. Furthermore, controlling stability and durability of the radial tire are improved, thereby reducing costs of maintenance of the passenger car.
