The overlapped screw holes 84a, 83a, 84b are fastened and fixed by screws 85.

  For example, as described in Patent Document 1, a method of fixing a molded product panel (a vessel) to a chassis main body with screws using a side plate as another component has been proposed.

  As described above, the conventional method of fixing a molded product panel to a sheet metal chassis or molded product chassis is fixing with screws, or fitting of concave and convex portions of a locking fitting fastening portion between molded products. The assembly structure is different. This is because it is difficult to form a groove or protrusion optimal for fastening because it is difficult to form a fine shape, and the molded product needs to have a wide fitting width in order to increase the assembly strength. Because. With these assembly structures, the molded product panels can be securely fitted and fixed to the respective chassis.

Thus, by providing the level difference T, the molded product panel 2 and the molded product chassis 21 or the molded product panel 2 and the sheet metal chassis 41 can be assembled without any level difference on the outer peripheral surface.

  In the above description, the process of assembling the molded product panel into the molded product chassis and the sheet metal chassis has been described in the order of assembling the molded product panel after combining the upper and lower chassis. However, the order of assembling is not limited to this, and a molded product panel may be attached to the lower chassis, and the upper chassis may be assembled by a predetermined method after being finally combined.

  As described above, in this embodiment, the sheet metal chassis is assembled to be fitted and assembled to the panel assembling groove 4 or the sheet metal chassis 41 for fitting and assembling to the molded article chassis 21 provided together with the molded article panel 2. By the projection 6, the molded product panel 2 can be alternatively assembled to either the molded product chassis 21 or the sheet metal chassis 41.

  In this embodiment, the molded product panel 2 is provided with the panel assembly groove 4 and the molded product chassis 31 is provided with the panel assembly projections 22a and 22b. However, this configuration may be reversed. That is, as shown in FIG. 2 (e), a panel assembly protrusion 4 'may be provided on the molded product panel 2, and panel assembly grooves 22a "and 22b" may be provided on the molded product chassis.

  Moreover, although the panel shape was made into the substantially rectangular shape panel, different shapes, such as an ellipse shape other than a rectangle, and another polygon shape, may be sufficient. In that case, needless to say, the device main body is configured by using a molded article chassis having an opening corresponding to the shape or a sheet metal chassis.
