PROBLEM TO BE SOLVED: To provide a baton elevator which can provide an appropriate assisting force according to the operation condition of a hand-drawing baton. SOLUTION: The baton elevator which ascends and descends a baton according to the operation of a hand drawing rope, has an electric winch (a baton driving means) 10 t provide an assisting force for ascending and descending the baton, a load balancing state controller 53 to set the bas assisting force instructing values, Fub and Fdb, which counter the gravity, an operation assisting force regulator 52 to set the operation assisting force, sensors 31 and 32 to detect the tension (operating force) given to the rope, Fu and Fd, and a controller 40 which calculates the operation assisting force setting values for ascending and descending the baton according to the tension Fu and Fd, and controls the electric winch 10 according to the assisting force setting values values obtained by adding the base assisting force setting values, Fud and Fdb, and the operation assisting force setting values.
