The present invention relates to an integrated fishing bobber and a method for manufacturing the same, and more particularly, to an integrated fishing bobber and a manufacturing method of the fishing bobber connected to a fishing line so as to sense fishery, which are integrally formed by a molding method and a method of manufacturing the same. It is about.

A fishing bobber consists of a bobbin body which generates buoyancy in water, and a bobbin installed longitudinally to this bobbin body.

The tail body is formed in a streamlined shape so that the resistance is reduced in the process of getting into the water and the process of leaving it in the water. Consists of a lower connection portion coupled to the fishing line connected to the fishing line.

On the other hand, wood is mainly used for paulownia, bamboo, sugi, balsa wood, etc. in consideration of buoyancy characteristics.Because wood has the property of easily absorbing moisture, a waterproofing agent such as varnish is applied to the surface of the body. It is common to use.

However, when the waterproofing agent of the tailing body is peeled off due to repeated use or impact, moisture penetrates and absorbs the wood, and as a result, the buoyancy of the tailing body is weakened, thereby degrading or losing the function of the bobber.

Accordingly, recently, a fishing bobber manufactured using a composite material having water resistance, as shown in Korean Laid-Open Patent Publication No. 2003-0030076, has been proposed.

A fishing bobber using a composite material is formed by grinding a molded article of a composite material obtained by mixing rubber, synthetic resin, and foaming agent in an appropriate amount to form a tailing body having a through hole, and inserting the tailing rod into the through hole of the tailing body in the longitudinal direction. After that, the adhesive is applied or injected on the upper and lower sides thereof, and the adhesive is dried to complete.

However, such conventional fishing bobbin is fixed to each other by the adhesive body with the adhesive body, the assembly is dependent on the manual work, and the adhesive or waterproofing agent has to be dried, the assembly time and production time is increased, productivity is reduced, the use of adhesive There was a problem that caused environmental pollution or industrial accidents.

In particular, during the fishing process, rocking and shock repeatedly act on the bobber, and the water is infiltrated by weakening or cracking of the adhesive that fixes the bobber body and the bobber as the acquisition and departure operations are repeatedly performed. There was a problem that occurred.
