The present invention relates to a wire sheave for stage equipment and a manufacturing method thereof, wherein a supporting disk made of metal is integrally provided inside a sheave made of synthetic resin, thereby preventing damage to or deformation of the sheave caused by the strong tensile force of a wire. To achieve the purpose, the present invention comprises: two sheave main bodies (10, 10') made of synthetic resin and forming a circular shape by forming a pair; a bearing part (20) provided at a central portion to support the rotation of the sheave main bodies (10, 10'); and a supporting disk (30) made of metal and formed between the sheave main bodies (10, 10') with a smaller diameter than the sheave main bodies (10, 10').

    본 발명은 무대 장치용 와이어 활차 및 그 제조방법에 관한 것으로서, 합성수지 재질의 활차 내부에 금속 재질의 지지원판이 일체로 구비됨으로써 와이어의 강한 인장력으로 인한 활차의 손상 내지는 변형 발생이 방지되는 효과를 나타낸다. 이를 실현하기 위한 본 발명은, 2개가 쌍을 이루어 원형의 형상을 이루는 합성수지 재질의 활차 본체(10,10')와; 상기 활차 본체(10,10')의 회전을 지지하기 위해 중앙부위에 구비되는 베어링부(20)와; 상기 활차 본체(10,10')보다 작은 지름을 이루어서 활차 본체(10,10') 사이에 구성되는 금속 재질의 지지원판(30);을 포함하는 구성을 이루는 것을 특징으로 한다.
