The present invention relates to a fastening device between a lower arm and a knuckle for an automobile, capable of simultaneously obtaining anti-dive performance and impact improvement performance. That is, the present invention is to provide a fastening device between a lower arm and a knuckle for an automobile, which may simultaneously obtain anti-dive performance and impact improvement performance by improving a fastening structure between the lower arm and the knuckle to a screw structure which can move the knuckle backward during bump operation so that the amount of farward movement of a wheel is reduced as the knuckle is moved backward by the pump operation during braking even if the angle (ε) between a line connecting both ends of a lower arm of a front wheel and the ground is increased.

    본 발명은 안티 다이브 성능 및 임팩트 개선 성능을 동시에 얻을 수 있도록 한 자동차용 로워암과 너클 간의 체결 장치에 관한 것이다. 즉, 본 발명은 로워암과 너클 간의 체결 구조를 범프 동작시 너클을 후방으로 이동시킬 수 있는 스크류 구조로 개선하여, 전륜 로워암의 양끝 지점을 이은 선과 지면 간의 각도(ε)를 증대시키더라도, 제동시 범프 동작에 의하여 너클이 후방 이동됨에 따라 휠의 전방 이동량을 줄일 수 있도록 함으로써, 안티-다이브 성능과 임팩트 개선 성능을 동시에 얻을 수 있는 자동차용 로워암과 너클 간의 체결 장치를 제공하고자 한 것이다.
