The present invention relates to a fishing bobber, and more specifically, the buoyancy of the fishing bobber is cut out several times in accordance with the state of the reservoir or the depth of the river or the water pressure to remove the bubbling (lead weight of the lead material) several times to adjust the buoyancy. Is related to fishing bobbers that can drastically control the buoyancy control of fishing bobbins even without scraping lead rods or using them. Conventionally, in order to control the buoyancy of fishing bobber by cutting the bondol several times, water pollution is serious on the lead bondol, which is a heavy metal, and according to the government policy, water pollution is prevented and environmental protection and In addition, the focus is on preserving the health of the people, and it is easy to control the buoyancy of the bobber with water only without cutting the lead rods. In addition, since 2012, the use of lead products has been replaced with bronze or iron, and these metals have strong strengths, so they are difficult to control buoyancy by cutting or grinding. In order to improve this, In order to achieve the above object, the present invention, in order to adjust the buoyancy of the bobber, the material is plastic, the bobber body is formed inside the empty space is buoyancy is formed, the inside of the body is inserted into the piston piston ring attached to the end of the piston Since there is no gap between the body and the body, the piston reciprocates like a syringe to inhale or discharge water into the body. The water inside the body is sucked in and the space in the body is reduced according to the amount of water sucked to adjust the buoyancy of the fishing bob. It adjusts buoyancy by inhaling or discharging water inside by reciprocating motion.
