PROBLEM TO BE SOLVED: To provide a movable bracket which can sufficiently widely set an insulation area on an electric pole and does not need to handle work as the high-voltage live wire proximity work. SOLUTION: The movable bracket (100) is composed of movable bracket mounting metal fittings (101, 103, 105, 102, 104, 106) for mounting the whole of the movable bracket (100) to the electric pole, a trolley wire supporting structures (120 or the like) for directly supporting the trolley wire (122), a plurality of pipe materials (107, 108) for bridging between the movable bracket mounting metal fittings (105, 106 or the like) and the trolley wire supporting structures (120 or the like), and insulators (113, 114) for insulating between the trolley wire supporting structures (120 or the like) and the movable bracket mounting metal fittings (105, 106 or the like). In the movable bracket (100), the insulators (113, 114) are disposed so that the movable bracket mounting metal fittings (105, 106 or the like) and the insulators (113, 114) will not directly contact with each other.
