Abstract
A festoon device includes a frame, which extends vertically, an upper pulley, which is rotationally supported by an upper part of the frame, and a lower pulley, which is rotationally supported by the frame below the upper pulley and is selectively moved up and down. The frame rotationally supports two auxiliary pulleys, which are arranged at a position closer to the frame than the upper pulley and the lower pulley. The festoon device is configured such that a wire is looped about the upper pulley and the lower pulley after being looped about the auxiliary pulleys.
