Reference numeral 28 denotes a storage battery installation space in which a pair of arc-shaped storage batteries 23.23 are installed, which is formed between the instrument main body 18 and the cylindrical case 1, and the storage batteries 23.23 are attached to the lower surface of the bottom of the case 1. A restraining plate 24 prevents it from falling.

Further, a wire connection space 25 adjacent to the lower part of the cylindrical case 1 is formed within the instrument body 18 .

Furthermore, the appliance body 18 has a mounting flange 26 bent outward at its lower open end and a mounting piece 27 provided on the appliance body 18 that is vertically adjustable, and can hold a field edge such as the ceiling of a structure. It is attached and installed.

Next, the operation of this embodiment will be explained.

To attach the wiring boards 8 and 9 to the cylindrical case 1, insert the tips of the wiring boards 8 and 9 into the open end of the cylindrical case 1 along the protrusions 5 and 5 or the protrusions 6 and 6, respectively. Thus, one side of each wiring board 8°9 is locked to the inner side of the cylindrical case 1, and the other side is locked to the protrusions 5, 5 or 6, 6, and the wiring board 8.
, 9 are housed and held in the cylindrical case 1 parallel to its axial direction.

Then, the wiring boards 8 and 9 are attached to the protrusions 5 and 5 on the cylindrical case 1.
Alternatively, the wiring boards 8 and 9 can be attached to the cylindrical case 1 by simply inserting them along the protrusions 6 and 6, making the operation easy and preventing the wiring boards 8 and 9 from moving toward the inner circumference of the cylindrical case 1. can be done reliably.

In this state, the cylindrical case 1 is attached to the top 19 of the device main body 18, and the storage batteries 23 and 23 are installed in the storage battery installation space 28.

When one wiring board 8 is used, a pair of protrusions 5, 5 may be provided as shown in FIG.

Further, in the embodiment, the projection 5 of the cylindrical case 1.
5. 6. 6 is formed by cutting and raising the side surface of the cylindrical case 1, but this protrusion 5. 5. 6. 6 may be formed by a punched bead or dowel, or the protrusion may be formed by fixing another member by welding or the like.

Further, the cylindrical case 1 is not limited to the cylindrical case 1 having a circular cross section as shown in the above-described embodiment, but may be, for example, a cylindrical case 1 having an oval cross section as shown in FIG. Alternatively, as shown in FIG. 5, the cylindrical case 1 may have a rectangular cross section, or as shown in FIG. 6, the cylindrical case 1 may have a triangular cross section. .

It should be noted that the same parts as those in the above-mentioned embodiment are given the same reference numerals and the explanation thereof will be omitted.

In the case shown in FIGS. 4 to 6, the wiring board 8 is inserted from the open end of each cylindrical case 1.
It is necessary that one side of the end of the case 1 is locked to the inner side of the case 1 that is narrower than the width of the wiring board 8, and the other side is locked to the protrusions 5, 5.

As a reference example, in FIG. 5, the wiring board 20
