PURPOSE: An unwinding device of a wire, a cable, etc is provided to prevent a tangle of a wire, thereby reducing time for organizing the tangle of the wire. CONSTITUTION: A bobbin comprises an upper bobbin(21) and a lower bobbin(22). A main body cover(30) rotates to be fixed with a hinge(33). A tensioner(40) supports an external diameter of a wire roll by using a spring. The tensioner is extended between an upper wing(23) and a lower wing(24) of the bobbin with a spring(42).
