The present invention relates to an automatic pulling apparatus of a fishing line. The automatic pulling apparatus of a fishing line of the present invention has guide passages in upper and lower portions of a body, which has a cross-section square shape, and has a guide roll installed in a rear internal side of the body. An operating member is inserted into the upper guide passage to be moved back and forth. One end portion of the operating member is fixed into the guide roll and the other end portion winds a flexible band fixed into the operating member. An engagement member having an engagement portion and a fixing portion is installed in a lower part of a front end portion of the body. An operating member having a support portion and a connecting support is installed in a lower portion of the body. Since a tensile string, connected to the fishing line, is installed in the connecting support, the tensile string operates the operating member when a fish bites and pulls the fishing line. The operating member operates the engagement member, so the fish is caught by pulling the fishing line while a pulling member is moved by retraction of the flexible band when the engagement portion of the engagement member gets out of a protrusion of the pulling member.COPYRIGHT KIPO 2015본 발명은 낚시줄 자동 당김 장치에 관한 것이다.본 발명 낚시줄 자동당김 장치는 단면 사각형으로 구성되는 본체의 상하부에 가이드 통로를 구성하고 본체의 후방 내면에 가이드롤을 설치하며 상부 가이드 통로에는 전후방향으로 이동될 수 있도록 작동부재가 끼워며 가이드롤에는 일단부가 고정되고 타단부가 작동부재에 고정된 신축밴드를 권취 시킨다.본체의 선단부 하방에는 걸림부와 고정부를 구비한 걸림부재가 구비되고 그 하부에는 받침부와 연결대를 구비한 작동부재가 구비되며 연결대에는 낚시줄과 연결되는 인장끈이 구비되어 물고기가 낚시를 물고 당기면 인장끈이 작동부재를 동작시키고 작동부재가 걸림부재를 동작시켜 걸림부재의 걸립부가 당김부재의 걸림턱에서 벗어나면서 당김부재가 신축밴드의 수축력에 의하여 이동되면서 낚시줄을 당겨서 물고기가 걸리게 되는 것이다.
