The hinge installation work is very time-consuming, and the latter welding method requires equipment such as a welding machine and requires high welding skill. Since there are many, there was a problem that the manufacturing cost was high. In addition, since multiple hinges are usually used, according to the above-mentioned conventional method, it is very difficult to align the rotary cores of the hinges in every case, and it is very difficult to obtain mounting accuracy, and the number of parts is large, so management is difficult. It was troublesome. Also, in order to improve the appearance, extra work such as blindfolding and painting is required.In addition, since the hinges are made of steel and the individual weight is heavy, the weight of the entire case increases and the steel hinges are long-term. There was a problem that rust was generated by use. Further, when the hinge is attached by welding, there is a problem that it is very troublesome to repair when the outer surface plate of the case constituent panel is damaged.
