As shown in FIGS. 5(a) and 5(b), two diagonal corners 19 of the holding piece 17b are chamfered in an R shape. As a result, when the holding piece 17b is rotated from the non-engaging position to the engaging position, the corner portion 19 does not interfere with the inner surface of the side wall portion 5b of the lower duct portion 5 so that the rotating operation can be performed smoothly. can.

When trying to insert the holding piece 17b of the second holding portion 16b into the lower duct portion 5, as shown in FIG. may overlap. In this case, if the positions of the lighting fixtures 10 are shifted so that the positions of the two do not overlap each other, a gap is formed between the adjacent lighting fixtures 10 and the appearance of the lighting system 1 deteriorates.

In contrast, in the lighting fixture 10 of the present embodiment, the position of the second holding portion 16b can be slid in the arrow B or C direction along the longitudinal direction of the housing 12 . Therefore, by sliding the second holding portion 16b to a position where it does not overlap with the connecting member 3 and holding it in the wiring duct 2, the lighting device 10 can be attached at a desired position. As a result, the lighting fixture 10 can be attached without leaving a gap between adjacent lighting fixtures 10, and the appearance of the lighting system 1 can be improved.

In the above description, an example in which the second holding portion 16b of the pair of holding portions 16a and 16b is slidably provided has been described, but the present invention is not limited to this. Only the first holding portion 16a may be slidable, or both the first and second holding portions 16a and 16b may be slidable.
