PURPOSE: A coil frame for transformer is provided to prevent the electric power loss due to the distortion of winding state by providing a lateral frame and an end plate between a trans coil and a field core. CONSTITUTION: Upper and lower frames(10,20) are provided with bent-up units(11,12) formed on both sides thereof so that a field core is reached to good condition, and comprised of fixing units(12,22) formed with a bolt hole on both sides of the bent-up units(11,12). A lateral frame(30) is coupled to both ends of the bent-up units(11,12) of the upper and lower frames(10,20), provided with a support bar(31) so as to bind the upper and lower frames(10,20), and comprised of a bolt hole on upper and lower ends of the support bar(31). An end plate(40) is provided on an inner side of the lateral frame(30), intervened between an outer surface of a trans coil and an inner surface of the field core, and prevents the distortion of winding state due to pressure of the side frame.
