The present invention is a baitcasting reel having a waterproof structure for the drag washer that can significantly increase the durability of the drag washer by applying a simple waterproof structure to block the inflow of seawater into the drag washer to prevent damage to the drag washer by sea water It is about. The baitcasting reel having the waterproof structure for the drag washer according to the present invention, the main body to form a frame, the cover is coupled to both sides of the main body, one end is rotatably coupled to one side of the main body and the other end is one side A spool shaft protruding outwardly through the cover and having a drive gear, a handle provided at the other end of the handle shaft, and a spool gear rotatably installed at the main body and engaged with the drive gear; A spool which is integrally formed on the spool shaft and forms a winding drum of the fishing line, a winding guide installed on the main body and guiding the fishing line wound on the spool, and a backlash installed at the end of the spool shaft and backlashing the spool. Brake mechanism for adjusting the rotational force of the spool to prevent the phenomenon, and dragging on the opposite side of the drive gear on the spool shaft , The sleeve washer, the sleeve and the drag adjustment knob are sequentially formed, the rotational resistance of the drive gear by moving the sleeve, the sleeve washer and the drag washer toward the drive gear in accordance with the rotation operation of the drag adjustment knob Drag control mechanism for adjusting the speed that the fishing line is released from the spool by adjusting the, and is coupled to the drive gear and comprises a waterproof ring member to block the inflow of seawater to the drag washer.본 고안은 드래그와셔로의 해수의 유입을 차단하여 해수에 의한 드래그와셔의 손상을 방지하는 간단한 방수구조를 적용함으로써 드래그와셔의 내구성이 대폭 증대될 수 있도록 한 드래그와셔용 방수구조를 가지는 베이트캐스팅릴에 관한 것이다.본 고안에 따른 드래그와셔용 방수구조를 가지는 베이트캐스팅릴은, 프레임을 형성하는 본체와, 상기 본체의 양측에 결합되는 커버와, 그 일단은 상기 본체의 일측에 회전가능하게
