Abstract

본 발명은 내충격, 내진동 및 체결력 강화 구조를 갖는 나사에 관한 것으로, 특히, 나사산의 중심을 기준으로, 나사산의 진입 방향 빗면을 이루는 전측플랭크(flank)면의 각도가, 나사산의 후퇴 방향 빗면을 이루는 후측플랭크면의 각도에 비해 작게 형성되고, 후측플랭크면은 경사 구간 내에서 수평 방향으로 단층 형성된 평탄부를 구비하여, 나사와, 나사에 대응하여 상호 체결되는 암나사 사이에서의 접촉 면적을 확장하는 형상으로 이루어져, 외부 충격으로 인한 상, 하, 좌, 우 방향의 진동을 억제하여 나사 체결 후의 자체 풀림 현상을 방지함은 물론, 반복 사용으로 인한 풀림 토크(torque) 저하 문제를 효과적으로 방지할 수 있는 기술에 관한 것이다.
