Further, FIGS. 10 and 11 show a tubular member (5) and a left front plate (1b) of the battery storage unit, and the elastic piece (50) projects from the upper and lower surfaces of the tubular member (5). I'm letting you.
In FIG. 10, a convex portion projecting forward is provided at a protruding end portion of a leaf spring portion (50a) projecting upward and downward from the upper and lower surfaces near the front open end of the tubular member (5) to press the cylinder member (5). It is a part (20b), and the protruding end of the convex part presses the back surface of the left front plate (1b) by the elastic recovery force of the leaf spring part (50a).
In FIG. 11, one leaf spring is curved in a substantially U-shape to form an elastic piece (50), which protrudes most forward of the substantially U-shaped leaf spring portion (50a). The bent end portion functions as a pressing portion (20b).

The elastic pieces (20) shown in FIGS. 8 and 9 may be provided on the upper and lower sides of the case frame (2). Similarly, the elastic pieces (50) shown in FIGS. 10 and 11 may be provided on the tubular member (5). ) May be provided on the left and right of the front open end.
The elastic piece as the pressing means is not limited to the above shape, and has another shape as long as it has a leaf spring portion that elastically deforms back and forth and a pressing portion that presses the back surface of the front plate. But it's okay.
Further, the pressing means is provided on the opposite side or surface of the peripheral edge of the front open end of the case frame (2) or the tubular member (5), one by one or two by the same number, but on one side. One may be provided in a staggered manner, such as two on the other side.

As described above, according to the present embodiment, the operating members as the electronic unit (29) and the battery storage unit (59) include the case frame (2) and the tubular member (5) as the respective mounting portions. The locking means locks on the back surfaces of the left and right front plates (1a) and (1b) to prevent the operating member from moving backward, and the pressing means also prevents the operating member from moving forward. Therefore, in consideration of mountability, rattling of the operating member can be prevented even if a gap is formed between the operating portion and the opening or between the locking projection and the locking hole. Further, since the pressing means elastically presses the back surfaces of the left and right front plates (1a) and (1b) in the locked state, the operating members can be attached to and removed from the left and right front plates (1a) and (1b). It is easy and does not reduce workability.
In the above-described embodiment, the table stove in which the operation panel is provided on the front surface of the appliance has been described, but the present invention can be applied as long as the operation panel is provided on a part of the constituent surface of the appliance. For example, the present invention can be applied to an operation panel of a heater or the like in which an operation unit is provided on the upper surface of the appliance.
