PURPOSE: A device for supporting a movable structure is provided to improve working efficiency by stably supporting a long structure with a roller unit. CONSTITUTION: A device(100) for supporting a movable structure is composed of a rest(110), a support unit(120) formed at the top of the rest, and a roller unit(130) coupled to the top of the support unit and supporting the structure. The support unit includes a first cylindrical body(121) extended from the center of the rest upward, and a second cylindrical body(122) slidably inserted into the first cylindrical body and coupled to the roller unit. The roller unit includes a roller holder(131) coupled to the support unit, and a roller(132) fixed to the roller holder and contacting with the structure.
