The present invention relates to a fishing weights assembly. According to the present invention, the fishing weights assembly enables a snell to be adjusted in length or fixed easily and quickly so a location of a hook is easily adjusted according to the type of bait or fishing conditions. The fishing weights assembly also enables easy and precise adjustment of the overall weight of the sinker. The fishing weights assembly according to the present invention includes: an upper body which has a ring for connecting a fishing line on an upper portion and an internal screw hole on a lower portion； a moving body which has an external screw inserted in the internal screw hole of the upper body with a screw-fitting and a guide groove forming a path for guiding a hooked snell to the inside of the upper body while the external screw is inserted in the internal screw hole of the upper body with the screw-fitting； and a rotating body which is located on the lower portion of the upper body to be inserted in an outer portion of the moving body and rotate the moving body and has a support body formed to correspond to the guide groove in shape to be inserted in the guide groove with the snell guided to the guide groove of the moving body in the middle. As the moving body moves in a vertical direction with respect to the rotating body by the rotation of the rotating body, the snell guided to between the guide groove and the support body is fixed or released and adjusted in length. The upper body is formed to be separated as an upper part and a lower part and accommodates multiple sinkers in the upper part and the lower part.본 발명은 목줄의 길이 조절 및 고정작업이 매우 간단하고 신속하게 이루어져 미끼의 종류 및 낚시 조건에 따라 바늘의 위치를 편리하게 조절할 수 있으며, 추의 전체 중량 조절작업을 매우 편리하게 함과 동시에, 매우 미세한 양까지 정밀하게 조절 가능한 낚시용 무게추 조립체를 제공한다.본 발명의 낚시용 무게추 조립체는, 상면에 낚시줄을 연결하기 위한 고리가 구비되고 하면에 암나사구멍이 형성된 상부체와, 상부체의 암나사구멍에 나사맞춤하는 수나사부가 형성되고, 수나사부가 상부체의 암나사구멍에 나사맞춤되어 삽입된 상태에서 바늘이 달린 목줄을 상부체 내부로 안내하기 위한 통로를 형성하는 안내홈을 구비한 이동체와, 상부체의 하부에 위치하고 이동체의 외측에
