Zusammenfassung:	The present invention provides a piston for improving tensile strength of a seat belt wire. To achieve this, according to the present invention, the piston comprises: a fixing groove of which one side portion and the other side portion are penetrated for a wire to be inserted thereinto; an embossed portion having a recessed shape formed by pressing a part of one side portion thereof; and a protruding portion protruding to an internal direction from an internal wall of the fixing groove by the embossed portion. 본 발명은 안전벨트용 와이어의 인장강도를 향상시키기 위한 피스톤을 제공하는 것이다. 이를 위해, 본 발명은 와이어가 삽입되도록 일측부와 타측부를 관통하는 고정홈; 일측부의 일부를 프레싱하여 형성되는 요입된 형상의 엠보; 및 엠보에 의해 고정홈의 내벽으로부터 내측방향으로 돌출되는 돌출부;를 포함하는 것을 특징으로 하는 피스톤을 개시한다.
