Abstract

PURPOSE:To obtain a structure which has attained a firm junction in the direction where the junction is separated, by providing a hook piece on the inside of a bending part of one metallic plate, forming a slit on the other metallic plate, doubling both of them, and performing a curling work. CONSTITUTION:When forming an internal case, etc. of an electronic range, a bending part 203 bent backward from a main surface 202 is formed on the circumferential edge of an opening part of a front plate 5, and on one part of the bending part 203, a hook piece 201 is formed by cur-raising so as to be opposed to the main surface 202. On the other hand, from an end edge part 205 of the first overhang part 204 of a drum plate 10, a bending part 206 is formed, and on a part of the bending part 206, a slit 200 is provided. When curling working is performed by doubling this front plate 5 and the drum plate 10, the tip of the hook piece 201 of the front plate 5 is opposed to one end 200a of the slit 200 of the drum plate 10, and contacts with it. In this way, it is possible to obtain a junction structure whose junction is not detached even if it is drawn or pushed in either direction as indicated with arrows X and -X.
