を備えたことを特徴とするロープ探傷装置。 In the rope flaw detector which inspects the presence or absence of damage to the wire rope by detecting the magnetic flux generated by magnetizing the wire rope,
A plurality of magnets that are installed at predetermined intervals in the movement direction of the wire rope and magnetize the wire rope by forming a pair of positive and negative magnetic poles;
A yoke for fixing the plurality of magnets at both ends and magnetically connecting them;
A detection coil installed between the plurality of magnets to detect the magnetic flux;
A magnetizing device that fixes the detection coil, has the plurality of magnets and the yoke, and constitutes a magnetic circuit as a whole to magnetize the wire rope;
A guide portion disposed so as to cover the detection coil and the magnetizing device, and guiding the sliding of the wire rope;
A rope vibration suppression jig that is attached to both ends of the guide portion and holds the sliding position where the wire rope slides and suppresses rope vibration,
