A fishing rod using lead is used by standardizing a certain unit weight, and when used, it is used to adjust the weight of the fishing chute by repeatedly throwing and retrieving the fishing gear that combines a fishing weight that is heavier than the buoyancy of the fishing bobber. In addition, it is used to reduce weight, but it is difficult to reuse because it cannot increase weight, and it is thrown away as a consumable material along with lead which is being scrapped, causing environmental pollution. The present invention replaces lead using a fishing weight, and manufactures fishing weight using materials less pollutant than lead, thereby reducing pollution caused by fishing activities and waste of resources by manufacturing fishing weights that can reuse components. In short, to increase the economics of the user. The fishing assembly designed as a representation for the realization of this is located between the fishing bobber coupled to the top of the fishing line (100) connected from the fishing rod and the fishing needle connected to the end of the fishing line is buoyancy of the fishing bobber and the infiltration of the fishing assembly 1 : 1 Adjust the weight by the combination of the weight adjustment weight (30) to be neutral buoyancy is used. Looking at the configuration, the fishing line 100 connected from the fishing bobber is coupled to penetrate through the receiving portion stopper 10 and the lower receiving portion 20a of the fishing weight assembly, the U-shaped incision groove in the weight control weight 30 Is combined with the necessary weight, the receiving portion stopper 10 in the open state to fill the internal space of the housing portion 20a without damaging the fishing line 100 using the incision groove, fishing fishing assembly line The stop rubber 20e penetrated to the fishing line 100 as a means for fixing at an arbitrary position is coupled to the lower end of the receiving portion 20a to prevent the fishing weight assembly from
