PROBLEM TO BE SOLVED: To provide a wire breakage detecting means of a wire rope that has a simple constitution, is inexpensive, and can check presence or absence of the wire breakage by easy work (visual observation). SOLUTION: The wire breakage detecting means of the wire rope has a pair of frame members 22 that have a recessed part and are openable or closable mutually, and paper 23 as an easily damaged member that is disposed in the recessed part of each frame member 22 and is damaged by abutting of a steel wire. The easily damaged member 23 has linear side sections 23a. When the pair of frame members 22 are closed, the side sections 23a of the easily damaged member 23 form a clearance D slightly larger than the diameter of the wire rope 4, and are disposed in parallel.
