PROBLEM TO BE SOLVED: To provide a hoisting device for elevator capable of improving workability of maintenance and inspection work of a rope, while securing safety of an operator.SOLUTION: A hoisting device for elevator includes: a main sheave around which a rope is wound which suspends a car provided movably in a vertical direction in a hoistway of a building and a counterweight, in a hoistway; a motor for rotationally driving the main sheave; a first cover part for covering a turn part in the rope coming into contact with the main sheave from outside; and a second cover part continuing to the turn part and for covering from outside at least one of a pair of straight parts in the rope extending in a tangential direction with respect to the main sheave. At least one part of the second cover part is constituted so as to change the position between a state in which the straight part in the rope is covered and a state in which the straight part in the rope is exposed to the outside.SELECTED DRAWING: Figure 1
