Disclosed, as a sheave for an elevator for supporting and moving a flat belt that tows an elevator car, is the sheave for the elevator comprising: a flat part that supports the flat belt by being in direct contact and forms a movement path of the flat belt; and a groove machined in a circumferential direction at both end parts of the flat part, wherein the groove has a function of losing a support force for an end part of the flat belt that has reached the groove when the flat belt moves laterally to any one side along an axis direction of the sheave. Therefore, the present invention is capable of having an effect of enabling in designing a lightweight and compact traction machine.

    엘리베이터 카를 견인하는 플랫벨트를 지지하고 이동시키기 위한 엘리베이터용 시브로서, 플랫벨트가 직접 접촉하여 지지되며 플랫벨트의 이동 경로를 형성하는 평탄부; 및 평탄부의 양단 부위에 원주 방향으로 가공되는 홈을 포함하고, 홈은 플랫벨트가 시브의 축방향을 따른 어느 일측으로 횡이동하였을 때 홈에 이른 플랫벨트의 단부에 대한 지지력을 상실케 하는 기능을 하는 것을 특징으로 하는, 엘리베이터용 시브가 개시된다.
