The present invention relates to a coil spring-shaped steel cord and a tire including the same. According to the present invention, the steel cord is manufactured by twisting an element wire in the form of a coil spring, and the cut elongation exceeds 10% or more. According to the present invention, the tire effectively prevents a puncture caused by an external impact and has the effect of reducing the propagation of corrosion because the impact resistance is increased by improving the elongation of a belt of the last layer of the steel cord tire manufactured by twisting the wire in the form of a coil spring.

    본 발명은 코일 스프링 형상의 스틸 코드 및 이를 포함하는 타이어에 관한 것이다. 본 발명에 따른 스틸 코드는 소선이 코일 스프링 형태로 꼬아져 제조되어, 절단신율이 10% 이상을 초과한다. 본 발명에 따른 타이어는 소선이 코일 스프링 형태로 꼬아져 제조된 스틸 코드타이어의 마지막 층의 벨트의 신율을 향상시켜 내충격성을 높임으로써 외부 충격에 의한 펑크를 효과적으로 방지하고 부식의 전파를 감소시키는 효과가 있다.
