PROBLEM TO BE SOLVED: To heighten speed of a refueling machine installed in a nuclear power plant. SOLUTION: Each wire rope 6a, 6b sent out from winding drums 3g, 3h connected to a hoisting motor 2 is connected to the second tubular member 1b from the outside or some one tubular member thereafter among each tubular member 1a-1f combined telescopically mutually, and pulleys 9a, 9b are installed on the upper end of each second tubular member 1b, and wire ropes 6c, 6d connected to the lower end of each outermost tubular member 1a are allowed to pass the pulleys 9a, 9b and connected to the lower end of each third tubular member 1c from the outside. As for tubular members thereafter, each wire rope 6e-6l is hooked over each pulley 9c-9j installed respectively on each tubular member similarly as the second tubular member, and as for the wire rope 6l, its one end is connected to a fuel gripper 5.
