Disclosed is an anti-loosening prevention end piece with a weight separation prevention function. According to the present invention, the anti-loosening prevention end piece comprises: a rod having predetermined length and having coupling parts formed on both sides to allow discs, which are weight bodies having different weights, to be coupled thereto; a first end piece coming in close contact with a disc fitted in the rod and having inclined parts formed on both sides; and a second end piece coupled to come in close contact with the inclined parts of the first end piece and having straight (-)-shaped flat parts formed on both sides. Accordingly, as the first end piece is mounted to come in close contact with the disc and the inclined parts of the first end piece and the straight flat parts formed on the side surfaces of the second end piece are coupled to form a predetermined distortion occurs on a second end piece side, a thread of the rod and a thread of the second end piece formed on the inner periphery of the second end piece come into close contact due to the distortion of the second end piece, thereby increasing mutual fixation force. 중량체 이탈 방지 기능을 갖는 풀림 방지 마구리가 개시된다. 이러한 본 발명에 의하면, 일정 길이를 이루며, 양측에 각각 다른 중량을 갖는 중량체인 원판이 결합되는 결합부가 형성된 봉체; 봉체에 끼워진 원판)에 밀착되며, 양면에 경사부가 형성된 제1마구리; 및 제1마구리의 경사부에 밀접되도록 결합되며, 양면에 일자(-)형 평면부가 형성된 제2마구리; 를 포함하여 구성될 수 있다. 이에 의해, 본 발명은 원판과 밀착되도록 제1마구리를 장착한 후, 제1마구리의 경사부와 제2마구리의 측면에 형성된 일자형 평면부가 밀착되도록 결합하여 제2마구리 측에서 소정의 뒤틀림이 발생하도록 함에 따라 제2마구리의 뒤틀림으로 인해 봉체 나사산과 제2마구리의 내주연부에 형성된 제2마구리 나사산이 밀착되도록 함으로써, 상호간 고정력을 향상시킬 수 있게 된다.
