DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to FIGS. 1 to 4, the same or corresponding parts are denoted by the same reference numerals.

FIG. 2 is an external perspective view of one embodiment of the present invention. In FIG. 2, a wireless remote controller 11 is provided at a distal end of a remote controller main body 12 made of a resin mold of ABS resin or the like and inside a transmission window. LED (light emitting diode)
On the other hand, a display section 14 for displaying room temperature, set temperature, time, and the like on a liquid crystal or the like is formed on the upper surface of the remote control main body 12 in the figure, and a concave step is formed. Various operation buttons 15a, 15a are provided on the bottom surface of the concave step.
Are formed, and a battery housing portion 16 for housing a battery is formed in a concave portion deeper than the concave step portion.

The battery housing 16 has an open upper surface, and the opening 1 and the concave step of the operation unit 15 are provided with a cover 1.
7 are detachably fitted and covered together.

As shown in FIG. 3, the battery housing 16 has substantially arc-shaped housing recesses 19a and 19b for housing two batteries 18a and 18b, respectively, substantially parallel to each other, as shown in FIG. The batteries 18a and 18b are elastically and electrically sandwiched in the axial direction by the coil-shaped receiving terminal 20a and the spiral receiving terminal 20b, and a relatively high height is provided between the storage recesses 19a and 19b. A, low
A partition projection 21 made of a resin mold or the like of BS resin or the like is integrally provided.

The partitioning protrusion 21 has a narrow portion 21a formed at one end (right end in FIG. 3) of which the side wall rises almost vertically to narrow the bottom width.

As shown in FIG. 1A, a part of the jumper wire 22 is buried in the bottom of the battery housing portion 16 and the cut portion 22a which can be cut is bent in a substantially U-shape. The partitioning projection 21 is buried so as to rise almost vertically within the narrow width portion 21a.

The jumper wire 22 is wired, for example, as shown in FIG.
For example, two resistors 23a and 23b are connected in series to 13, and one of the resistors, for example, 23b is connected before and after by a jumper wire 22 to short-circuit the resistor 23b, thereby reducing the electrical resistance. Therefore, by cutting off the upper end of the cut portion 22a of the jumper wire 22, the resistor 23b is inserted into the light emitting LED 13 and the transmission L
