An eleventh embodiment of the present invention is shown in FIG. That is, in this illumination device, in the eighth embodiment, the transparent acrylic plates that are the light guide members 16 and 17 are arranged in front of the straight tube lamps 1a to 1c. Since the direct light of the straight tube lamps 1a to 1c passes through the transparent acrylic plate, it does not interfere with the irradiation of the direct light. With such a configuration, the height of the instrument body 12 can be further reduced.

A twelfth embodiment of the present invention is shown in FIGS. 17 and 18. That is, in this illuminating device, in the eighth embodiment, the fixture body 12 has the attachment hole 22 and the removal preventing portion 23 for the wood screw 25 for attachment is provided at the edge of the attachment hole 22. As the slip-out preventing portion 23, a folded piece cut and raised in the instrument body 12 is used as an example, and a hole 24 that is aligned with the mounting hole 22 is formed in the slip-out preventing portion 23.

According to this embodiment, when the electric tool is used to mount the instrument main body 12, it is possible to prevent the wooden screw 25 from penetrating, which facilitates the construction. Therefore, even if the instrument body 12 is formed of a thin steel plate, the portion through which the wood screw 25 passes has a double thickness, so that the wood screw 25 can be prevented from penetrating. In this respect, when installing a wood screw with an electric drill, it was possible to penetrate through the back of the device, and it was necessary to hold it down by hand, making the construction complicated.

Note that not only the folded piece can be provided but also the knockout hole can be used. 19 and 20 are modified examples of the slip-out prevention portion 23, in which a taper portion 26 to be pressed against the head of the wood screw 25 is formed at the edge of the mounting hole 22 of the instrument body 12. When the wood screw 25 is tightened, the taper portion 26 falls in the direction of the arrow, and the size of the mounting hole 22 becomes smaller, so that the wood screw 25 is prevented from coming off.
