PURPOSE: A Simcheong is provided to easily grasp a weak biting, to reduce the influence of winds and tidal currents, and to enhance the weight of a float.CONSTITUTION: A Simcheong comprises a main body, an absorption fabric (13), a storage space, an integrated inlet (12). The absorption fabric is mounted in the main body, offsets buoyancy by absorbing moisture, and is stable regardless of injected liquid. The injected liquid can be accommodated in the storage space and can be discharged from the storage space. The integrated inlet is made of a special silicone and prevents water from entering the inlet. Buoyancy can be reduced by discharging air from the storage space. The Simcheong can be thrown a long distance and can avoid the influence of winds on the surface of water.COPYRIGHT KIPO 2013본 발명은 액체를 주입하여 부력과침력을 조절하는 장치로써대상어종의 약은 입질에도 그 파악이 용이하며 바람과 조류에 의한 영향을 적게 받으며.멀리 던져지는 찌의 무게를 높일 수 있다.
