The user does not see the outer surface of the right side wall 80e. At this time, even if the name plate is attached to the outer surface of the right side wall 80e of the battery case 13 that is pulled out, the user does not see the name plate, and the name plate is attached to the outer surface (left surface) of the left side wall 80d. And the user can see the nameplate.

  Further, when the gas stove 1 of the present embodiment shown in FIG. 8 is installed at the left back corner toward the wall, if the name plate is attached to the outer surface of the left side wall 80d, the battery case 13 drawn out The distance between the outer surface of the left side wall 80d and the left side wall is far enough for the user to enter, and the user can enter and work during this time, so the user can see the nameplate.

  If the case storage port 12a is formed at a position biased to the left of the left and right central portions of the front surface portion 12 of the housing 10, the right side wall 80e on the opposite side to the side on which the case storage port 12a is biased. The upper and lower lengths h1 may be substantially equal to the diameter of the battery, and the nameplate attaching portion 96 may be provided on the outer surface.

  Since only one nameplate needs to be attached, and it is not necessary to attach the nameplate to the side walls 80d and 80e on both sides, the nameplate attaching portion 96 is not provided on the other side wall 80e, and the vertical length h2 thereof is shortened. That is, when the vertical lengths of the side walls 80d and 80e on both sides are substantially equal to the diameter of the battery, it is difficult to insert and remove the battery, but if the vertical length h2 of at least one of the side walls 80e is shorter than the diameter of the battery. It is possible to take out the battery by inserting a finger from the side wall 80e side and pushing up the lower part of the side surface of the battery so that the battery can be easily taken in and out. In the present embodiment, since the vertical length h2 of the side wall 80e is approximately half the diameter of the battery accommodated therein, it is easy to put in and out, and the battery does not fall over and fall off the side wall 80e. .

  Further, a notch 97 into which a finger can be inserted may be formed at one or both upper and lower end edges of one or both of the left and right side walls 80d, 80e of the battery case 13. In this embodiment, FIG. As shown, a notch 97 is formed in the front end portion of the side wall 80e whose vertical length h2 is shorter than the diameter of the battery. Thereby, it becomes easy to take out the battery by inserting a finger from the notch 97, and it becomes easier to take out the battery by providing the side wall 80e whose vertical length h2 is shorter than the diameter of the battery. Of course, the notch 97 may be provided in the side wall 80d having the vertical length h1 substantially the same as the diameter of the battery. If the notch 97 is deepened, the battery can be easily taken out.

  In the present embodiment, the decorative panel 98 can be detachably provided on the front surface of the front wall 80f. The decorative panel 98 is made of a synthetic resin having a claw-like upper locking portion and a lower locking portion (not shown) on the upper and lower ends of the back surface, as shown in FIGS. 9 and 10. A locking projection 80g projects from the lower end surface of the front wall 80f, and the upper locking portion of the decorative panel 98 is locked to the upper end portion of the front wall 80f and the lower locking portion is locked to the locking projection 80g.
