The sliding guide 27 faces the elastic portion 25 'of the non-detection elastic contact terminal 25 and is formed at substantially the same height. That is, as shown in the drawing, a position 13 distance higher than the mounting height distance difference 12 between the elastic portion 25 'of the non-detection elastic contact terminal 25 and the elastic portion 26' of the detection elastic contact terminal 26. The sliding guide 27 is formed in the above.

Accordingly, when inserting the terminal portion 21 into the socket portion 24, the terminal portion 21 is sandwiched between the non-detecting elastic contact terminal 25 of the socket portion 24 and the sliding guide 27. To slide in
When the non-detection elastic contact terminal 25 is inserted into the terminal portion 21, the non-detection elastic contact terminal 25 presses against the inner wall surface on which the detection elastic contact terminal 26 is arranged. Can be eliminated.

Also, by using the above-described reflecting portion having the terminal portion and the socket portion and the holder as a lighting device, it is possible to provide a lighting device which can easily and reliably exchange a light source for a reflecting portion mounted at a high place. it can.

As described above, when the terminal is inserted into or removed from the socket, the terminal is inclined so that the discharge lamp can be reliably detected even when the terminal is inserted or detached, and the terminal is supplied to the discharge lamp. It is possible to provide a one-touch attachment / detachment device that can prevent unnecessary operation of the inverter circuit that generates the lighting power, and a lighting device using the one-touch attachment / detachment device.
