Zusammenfassung:The present invention relates to an elevating device, which may prevent heating or a reduction in a lifespan since there is no slip (friction) between wires and a pulley body. The elevating device includes a frame part, an elevation part elevated along the frame part, and a pulley part which elevates or drops the elevation part while rotating. The pulley part comprises: a pulley body which is provided to be rotatable in the elevation part; a first wire which has one side coupled to the pulley body and the other side coupled to the upper part of the frame part; and a second wire which has one side coupled to the pulley body and the other side coupled to the lower side of the frame part. When the pulley body rotates, the number of windings of any one of the first or second wire increases, and the other one is unwound from the pulley body and has a reduced number of windings, so that the pulley body is elevated or dropped. The elevation part elevates or drops with the pulley body. 본 발명은 프레임부와, 상기 프레임부를 따라 승강하는 승강부와, 회전하면서 승강부를 승하강시키는 풀리부를 포함하며; 상기 풀리부는 승강부에 회전 가능하게 구비된 풀리본체와, 일측은 상기 풀리본체에 결합되고 타측은 프레임부의 상부에 결합된 제1와이어와, 일측은 상기 풀리본체에 결합되고 타측은 프레임부의 하부에 결합된 제2와이어를 포함하여; 상기 풀리본체가 회전하면 제1와이어와 제2와이어 중 어느 하나는 풀리본체에 감기는 감김수가 증가하고, 다른 하나는 풀리본체로부터 풀려 풀리본체에 감기는 감김수가 감소하여 풀리본체가 승하강하고, 상기 풀리본체와 함께 승강부가 승하강하는 것을 특징으로 하는 승강기구에 관한 것이다.
