To improve work efficiency by fixing the end section of a main rope to at least one of multiple frames and multiple arms constituting the winding section of the main rope on the frames fixed to the end section of a disk-like circular base.

Four frames 13 made of a rectangular hollow rod are radially arranged around a circular base 11, and the frames 13 are connected to the end section of the circular base 11 by connecting shafts 12 and rotatably supported at one end. When arms 14 are located at the operating positions where they are perpendicular to the frames 13 and parallel with each other, they have an obtuse angle against the frames 13 and are made parallel with each other, and a winding section 27 winding a main rope is formed. Guides 15 are fitted to two opposite arms 13 at the positions slightly moved to the circular base 11 from the fitting positions of the arms 14, the tips of the guides 15 are formed into a U-shape, and the tip of the main rope is pinched by them. Clothespin-like rope grips 16 are adjacently fitted.
