The pressing projections 49 on the inner surface of the clamp portion 42 are respectively inserted into the electric wire insertion groove 46 and abutted on the power supply line 25 folded inside the electric wire insertion groove 46, and the power supply line 25 is connected to the base portion at the abutted portion. It is sandwiched between 41. As a result, the power supply line 25 is held by the mounting portion 1 that fixes the base portion 41, and is held in a stable state in the lighting device 700.

Since the power supply line 25 is folded back in the electric wire insertion groove 46 of the electric wire holder 4 made of resin, it does not come into contact with the edge portion of the electric wire insertion notch 13 which is notched in the mounting portion 1. Therefore, even if the processing finish of the mounting portion 1 is somewhat rough, the power supply line 25 does not directly contact the edge (edge portion) of the wire insertion notch 13 and is not damaged, and the reliability of holding the power supply line 25 is high. Nature is secured.

When the clamp portion 42 is tilted, the clamp portion 42 covers the electric wire insertion groove 46 and closes the electric wire insertion groove 46. This prevents the one surface side and the other surface side of the mounting portion 1 from communicating or opening through the wire insertion groove 46. Therefore, the light emitted from the LED 21 is prevented from leaking to the other surface side of the mounting portion 1 through the wire insertion groove 46, so that the light utilization efficiency can be improved and unnecessary light is emitted from the lighting device 700. Can be prevented.

It is maintained for a long time.

As described above, when assembling the lighting device 700 including the wire holder 4 of the embodiment, when the power supply line 25 connected to the light emitting unit 2 is routed from one surface side of the mounting portion 1 to the other surface side, The insertion groove 46 is inserted and folded back, a part of the folded back part is held by the holding part 45, and the clamp part 42 is tilted at the hinge part 43 before and after the holding part 45 to be sandwiched between the clamp part 42 and the base part 41. The power supply line 25 can be held only by work. Therefore, it is possible to quickly and easily hold the power supply line 25 in the lighting device 700 with moderation. Moreover, since the wire holder 4 can be integrally formed using a resin material, it can be manufactured at low cost.

When performing maintenance on the lighting fixture 100, the holding state of the power supply line 25 can be released by releasing the engagement between the first engaging portion 47 and the second engaging portion 48. When the electric wire holder 4 is defective, the fitting of the snap portion 44 with the mounting hole 14 of the mounting portion 1 can be released to easily remove the electric wire holder 4 from the mounting portion 1. Can be exchanged for.
