The present invention comprises a metal frame consisting of a plurality of vertical borders consisting of a circular or polygonal upper and lower borders to support the upper and lower borders spaced apart by a predetermined interval, and a mesh for surrounding the outside of the metal frame, In the trap consisting of a manned entry opening formed between the vertical border and the adjacent vertical border, the upper and lower borders of the trap are provided with an opening on one side while being wrapped with a net, but the cross section is circular and has elasticity The cover member is to be covered by a holding member for holding and surrounding the outside of the cover member, and the vertical border is to be covered by cover portions formed on both sides of the manned entry port injection-molded by a synthetic resin material, It is to provide a prefabricated trap having an inlet for a trap configured to be fixed by a cover member and a holding member, as well as the edges of the upper and lower support of the inlet, and the effect of the present invention makes it easy to attract blue crabs or mollusks. Therefore, it is easy to capture, but in the manufacture of the pot, most of the pot can be manufactured as an assembly type, thus minimizing manual work to achieve uniform quality, reducing manufacturing cost and manufacturing time, and coating to prevent corrosion of metal frames. The cover member can protect the covered covering, and it can cushion the impact to prevent damage to the pot. In addition, the cover member is made of synthetic resin, so it is less slippery to minimize collapse when the pot is loaded. It is a very useful invention that is very helpful in preventing safety accidents.본 발명은 원형 또는 다각형상의 상부테두리와 하부테두리로 이루어지고 상기 상부테두리와 하부테두리를 일정 간격 이격토록 지지하기 위한 다수개의 수직테두리로 이루어지는 금속프레임과, 상기 금속프레임의 외부를 감싸기 위한 그물망과, 상기 수직테두리과 인접하는 수직테두리의 사이에 형성되는 유인진입구로 이루어지는 통발에 있어서, 상기 통발의 상부테두리와 하부테두리는 그물망으로 감싸진 상태에서 일측에 개방부를 구비하되 단면이 원형이고 탄성을 갖는 커버부재에 의해 피복되도록 하고, 상기
