PURPOSE: A gear tooth wear measuring apparatus for a spline coupling is provided to minimize wear by checking the wear without disassembling the coupling portion with measuring the wear of a spline gear conveniently, and to prevent accidents by replacing the spline gear timely. CONSTITUTION: A wear measuring device of a spline coupling is composed of a wire drum part(100) having a wire drum connected to an outer spline(210) coupling to a driving unit and a supporting piece(150) and rotating horizontally; a spline coupling part(200) having the outer spline and an inner spline(220) combined inside the wire drum to transmit power; and a wear measuring part(300) having a gear unit installed in the central shaft of the outer spline to measure wear of spline teeth(211), and a scale indicator(340) and a scale display connected to the gear unit to display wear. Breakage and accidents are prevented by replacing the equipment timely and checking with measuring the wear.
