Abstract

A magnetizer configured to form a main magnetic flux path so as to include a set interval in an axial direction of a wire rope includes a first pole piece and a second pole piece, which are arranged so as to sandwich the set interval therebetween, each have a U-shaped cross section which is formed so as to surround the wire rope in a circumferential direction of the wire rope for about a ⅔ turn without coming into contact with the wire rope. When the wire rope is magnetized by the magnetizer, a leakage magnetic flux generated from the wire rope damaged portion is detected by a magnetic sensor.
