  However, the conventional door mounting structure 100 using the hinge fitting 104 is expensive because the hinge fitting 104 is used. Moreover, it is necessary to screw the hinge metal fitting 104 to the housing, the box member 101, and the door member 102, which takes time for assembly.

  On the other hand, the door mounting structure 110 that attaches the door to the conventional locking piece can be manufactured at a relatively low cost because a hinge is not used. However, it is necessary to project the storage portion 117 on the device-side frame piece 112 by welding or the like, which again takes time for assembly. Further, when the work is performed with the door 114 removed, the storage portion 117 protrudes from the surface of the device-side frame piece 112, so that there is a possibility that the worker's clothes may be caught during the work, resulting in an obstacle to the work. Further, the conventional door mounting structure has a small door opening angle of approximately 90 degrees. Therefore, there is also a problem that it is difficult to work in a state where the door is opened.

  Accordingly, an object of the present invention is to provide a door mounting structure that can be manufactured at an extremely low cost, is extremely easy to assemble, and can open the door at an opening angle of about 180 degrees, and a door mounting used therefor. It is to provide a member.
