It consists of a switch plate provided and a decorative plate whose outer periphery is bent and formed into a tray shape and is slidably provided by a claw portion that locks the protrusion, and the decorative plate is slid into the switch plate and the switch is The hook part of the plate is fitted into the support rib of the storage frame, and the plate is fitted into the storage frame. Next, when a screw is tightened from below the concave portion of the storage frame, it is screwed into the screw hole provided in the mounting boss of the switch plate, and only the switch plate moves downward, and the protrusion of the switch plate is attached to the storage frame. This reduces the number of screw fastening points, which reduces work time, improves work efficiency, and reduces material costs.

DESCRIPTION OF EMBODIMENTS Hereinafter, a case will be described in which an embodiment of the present invention is used in a rice cake making machine.

In FIGS. 3 and 4, reference numeral 15 indicates a support fitting made by bending a steel plate, 16 indicates a motor attached to the upper surface of the support fitting 15, and 17 indicates a support fitting 15 connected to the support fitting 15 via the electric motor 16. The steam tank is a steam generating device mounted on the top surface, and is equipped with a heating element 18 on the outer bottom, as well as a bearing 20 for a motor shaft 19 and an oil seal 21.

22 is a hopper detachably attached to the upper end of the steam tank 17 via a tank packing 23; 24 is a rotor detachably attached to the upper end of the motor shaft 19 passing through the hopper 22;
25 is a synthetic resin ceiling frame with one end fixed to the upper end of the steam tank 17 via a body packing 26 so as to cover the hopper 22, and a square frame projecting outward like a bay window on the side. A formed storage frame 27 is provided. A recess 28 that protrudes upward at the center of the lower surface of the storage frame 27 and has a through hole for screw insertion, and apertures 29 penetrating both sides of the recess 28 are provided, and support ribs 30 are provided on the inner surface of the upper part. .

Reference numeral 31 denotes a switch plate made of synthetic resin in which a switch 32 for switching to an electric circuit is inserted with a switch shaft 33 protruding outward from the inside of a flat surface, and a mounting boss 34 that fits into the recess 28 of the storage frame 27 is provided at the lower end. A protrusion 35 that fits into the opening 29 is provided, a hook 36 with an L-shaped cross section that is engaged with the support rib 30 is provided at the upper end, and protrusions 37 are provided on the outside of both sides.

Reference numeral 38 is a decorative plate made of a thin metal plate whose outer periphery is bent to form a tray shape, and a claw portion 39 having a U-shaped cross section fits so as to cover the protrusion 37 of the switch plate 31.
are provided on both sides, and an opening 40 through which the switch shaft 33 passes is provided in the flat surface.

41 is a switch shaft 33 protruding from the decorative board 38
42 is a support fitting 15, an electric motor 16, and a steam tank 17.
It has a bottomed cylindrical body that covers and protects the structural parts such as, and a cord box 43 that stores a power cord is inserted on the side, the upper end fits into the hanging part of the ceiling frame 25, and the bottom surface is connected to the legs 44. It has been concluded. 45
is a capacitor.

The installation procedure in the above configuration will be explained.

As shown in FIG. 5, insert the claw portion 39 of the decorative board 38 from above the protrusion 37 of the switch board 31, and move the decorative board 38 downward until the upper surface of the switch board 31 and the upper side of the decorative board 38 touch. The switch unit section 43 is moved.

Next, as shown in FIG. 6, FIG. 7, and FIG.
0 and the back wall of the top frame 25, and when the edge of the decorative board is fitted into the frame of the storage frame 27, the recess 28 of the storage frame 27 will be located below the mounting boss 34 and protrusion 35 of the switch board 31. It is locked at the position where the opening 29 and the opening 29 match.

Then, when the screw 43 is inserted into the recess 28 of the storage frame 27 and installed, the screw 43 is screwed into the installation boss 34, and only the switch plate 31 is pulled downward.
The protrusion 35 of the switch plate is located at the opening 2 of the storage frame 27.
9 and attach the switch unit 43. Finally, the switch knob 41 is press-fitted onto the tip of the switch shaft 33.

Therefore, the switch unit 43, in which the decorative plate 38 is slide-fitted to the switch plate 31, can be attached by tightening at only one place, which reduces the number of screws to be tightened, shortens work time, improves work efficiency, and saves material. It is possible to reduce costs.

Effects of the Invention As is clear from the description of the above embodiments, the switch board mounting device of the present invention slides and fits a decorative board onto a switch board into which a switch is inserted, and inserts this into a storage frame.
