The present invention relates to a magnetic locking type missile folding fin. According to the present invention, the magnetic locking type missile folding fin includes a plunger (11) accommodated in a magnetic hole bored in an upper fin fixing unit (2-1) of a lower fin (2). The plunger (11) protrudes from the lower fin (2) by magnetism between magnets (15, 16, 17) to fix an upper fin (1) unfolded. The plunger (11) is inserted into the magnetic hole by the magnetism by being covered by the upper wing (1) folded, and a structure is simplified in comparison with spring elasticity locking mechanism. Especially, an operation force before and after the operation is maintained to be constant by combination of an attractive force and a repulsive force between the magnets (15, 16, 17). Therefore, the excessive operation force causing operation impact can be solved.

    본 발명의 마그네틱 잠금방식 유도무기 접이식 날개는 하단날개(2)의 상단날개 고정부(2-1)에 뚫려진 마그네틱 홀로 수용된 플런저(11)를 구비하고, 상기 플런저(11)가 전개된 상단날개(1)를 고정하도록 마그네틱(15,16,17)사이의 자력으로 하단날개(2)에서 돌출되는 반면 접혀진 상단날개(1)로 가려져 자력에 반해 상기 마그네틱 홀로 삽입됨으로써 스프링 탄성력 잠금 메커니즘 대비 구조 단순화가 이루어지고, 특히 마그네틱(15,16,17)마그네틱(15,16,17)사이의 인력과 척력 조합으로 작동 전,후의 작동력이 일정하게 유지됨으로써 작동 충격을 주는 과도한 작동력 발생도 해소되는 특징을 갖는다.
