PURPOSE: A rebar binding device is provided to screw rebar to a coupler and firmly couple the rebar to the coupler, even if the cut part of the rebar is deformed or burr occurs. CONSTITUTION: A rebar binding device comprises first and second spacers(10,20), and a coupler. The first and second spacers are formed as a spiral shape. The first and second spacers are respectively coupled to the connecting ends of first and second rebar(1,2). The first and second rebar is screwed to the coupler so that the first and second rebar is connected. The coupler comprises first and second sockets(40,50). Screw threads are formed on the inner circumferential surfaces of the first and second sockets so that the first and second rebar is screwed.
