Abstract
A wire rope flaw detector includes a magnetizer having a pair of exciting magnets disposed on a back yoke such that polarities thereof are opposite to each other, and forming a main magnetic path in a predetermined segment in an axial direction of a wire rope; and a leakage magnetic flux detection section disposed in the predetermined segment in the axial direction, and detecting leakage magnetic flux generated from a damaged portion of the wire rope. Each of the exciting magnets are formed so as to have a cross-section of a shape that embraces the wire rope when each exciting magnet is cut along a plane perpendicular to the axial direction of the wire rope, and has magnetic orientation, on the cross-section of the exciting magnet, oriented from at least two directions toward the wire rope.
