Reference numeral 4 denotes a cover body, and this cover body 4 has a transparent cover part 6 formed in a dish shape with an opening 5 on the upper surface, and is arranged on the inner surface of the side wall facing each other at a distance from each other. Socket that forms the body 7.
7, a straight tube lamp to be attached to the socket 7, and a connecting portion 10 that is removably connected to the connector 3, and is formed to be detachably attached to the appliance body 1. There is.

To explain this cover body 4 in more detail, the light-transmitting cover portion 6 is, for example, milky-white and transparent, and is formed into a dish shape, and the base portion of the lamp 9 fits into the inner wall of the light-transmitting cover 6. An elongated box is provided with a socket 7 having four parts 11, and a ballast is housed in the box to form a lighting device 8. A connecting portion 10 having a connecting pin connected to a connecting piece of the connector 3 of the appliance main body 1 is provided at an end of the lighting device 8.

This cover body 4 is removably attached by engaging an engaging portion 12 provided on the transparent cover portion 6 with an elastic locking piece I3 provided on the instrument body 1. This engaging means may be one used for attaching the cover body in a conventional manner.

In this embodiment, the connector 3 and the connecting portion IO are configured to be electrically connected by attaching the cover body 4 to the instrument body 1.

14 is a lighting tube provided in the lighting device 8.

Next, the operation of this embodiment will be explained.

When attaching the cover body 4 to the instrument body 1, the cover body 4 is attached to the instrument body 1.
, and engage the engaging portion 12 with the elastic locking piece 13 of the instrument body 1. To remove the cover body 4 for lamp replacement or the like, it is sufficient to pull it down against the elasticity of the locking piece 13. Then,
Lamp replacement can be done easily using the cover body 4 placed on the floor or desk top. Furthermore, since the socket 7 is provided on the cover body 4, the lamp 9 can be easily positioned and mounted.
