To increases a friction force of a crawler and a wire-armored cable without increasing a contact length of the crawler 3 and the wire-armored cable 1, in a device for delivering the wire-armored cable by pressing the crawler 3 against the wire-armored cable 1 from upper and lower sides and by subjecting the crawler to orbiting movement.

A rigid member 11 formed of iron is arranged along a crawler 3 at the inner circumference side of the crawler 3 in a section in which the crawler 3 is brought into contact with a wire-armored cable 1, an electromagnet 12 is attached to a surface opposite to the crawler 3 of the rigid member 11, a force attracting an iron wire 1a of the wire-armored cable 1 to the side of the crawler 3 by a magnetic force of the electromagnet 12 in addition to a force generated by mechanically pressing the crawler 3 against the wire-armored cable 1 is generated, and a friction force between the crawler 3 and the wire-armored cable 1 is increased.
