PURPOSE: A transformer case capable of easily assembling and disassembling is provided to improve the working efficiency by fixing a front plate on a curving unit of a lower plate and assembling a left-and-right surface plate and an upper surface plate of the case. CONSTITUTION: Curving surfaces(17b,17c,17d) are formed on upper, lower, right, and left sides of a front plate(1). A piece hole(18) is formed on a center of a lower of the front plate(1). A curving surface(15) is formed on a front portion(5a) of a lower plate(5). A piece hole(18') corresponding to the piece hole(18) allows a curving surface to be welded on the lower plate(5). A length of the curving surface in horizontal is shorter than that of the curving surface(15) to form gaps into which the left and right curving surfaces(17b,17d) are inserted.
