In addition, about the lighting fixture 2, only the surface side of one side is shown. That is, only the 1st surface side is shown about the 1st lighting fixture 2-1, and only the 2nd surface side is shown about the 2nd lighting fixture 2-2. Moreover, both the 1st lighting fixture 2-1 and the 2nd lighting fixture 2-2 are the structures demonstrated based on FIG. 2 and FIG.
FIG. 5 is a view showing a state in which two lighting fixtures 2 are attached to the T-bar 1. FIG. 5A is a diagram viewed from the upper surface 10 side (A direction in FIG. 4). FIG.5 (b) is the figure seen from the side surface side (B direction of FIG. 4). FIG.5 (c) is a figure which shows only the 1st attachment member 4-1, the 2nd attachment member 4-2, and the T-bar 1 part of FIG.5 (b) simply.
The T bar 1 is formed in a substantially T shape. The T-bar 1 has a hanging portion 11 formed in a rectangular parallelepiped shape, a support portion 12 formed in a rectangular parallelepiped shape that is wider than the hanging portion 11 (W10 <W11), and a thin plate shape that connects the hanging portion 11 and the support portion 12. The intermediate part 13 is provided. The width W12 from the end of the support portion 12 to the opposite end of the hanging portion 11 is substantially the same as the width W9 of the first convex portion 5-1 and the second convex portion 5-2.
Two lighting fixtures 2 are attached to the T-bar 1. The first lighting fixture 2-1 has the T-bar 1 hooked on each first convex portion 5-1 of the first mounting member 4-1 so as to straddle from the C side to the D side in FIG. 4 or FIG. The first claw portion 7-1 at the tip of each first convex portion 5-1 is hung on the lower surface on the D side of the hanging portion 11 (see FIGS. 5B and 5C). And each 1st convex part 5-1 and each 1st nail | claw part 7-1 pinch | interpose the hook part 11, and the 1st lighting fixture 2-2 is fixed to T bar 1. As shown in FIG. Similarly, the 2nd lighting fixture 2-2 has the 2nd convex part 5-2 which the 2nd attachment member 4-2 has so that it may straddle from the D side of FIG. 4 or FIG. The second claw portion 7-2 at the tip of the second convex portion 5-2 is hung on the lower surface on the C side of the hanging portion 11 (see FIGS. 5B and 5C). And each 2nd convex part 5-2 and each 2nd nail | claw part 7-2 pinch | interpose the hook part 11, and the 2nd lighting fixture 2-2 is fixed to T bar 1. As shown in FIG.
Moreover, while each convex part and each nail | claw part pinched | interpose the hook part 11 of T-bar 1, each support part 12 of T-bar 1 contact | abuts the 1st surface or 2nd surface of the fixture main body of the lighting fixture 2, and each It prevents that a nail | claw part remove | deviates from the hook part 11. FIG.

ここで、図５（ａ）に示すように、第１照明器具２−１の第１取付部材４−１の第１凸部５−１（１）と第２照明器具２−２の第２取付部材４−２の第２凹部６−２とは嵌り合い、第１照明器具２−１の第１取付部材４−１の第１凹部６−１と第２照明器具２−２の第２取付部材４−２の第２凸部５−２（１）とは嵌り合って、Ｔバー１に取り付けされる。つまり、上記の通り、照明器具２（第１照明器具２−１、第２照明器具２−２）は、第１取付部材４−１と第２取付部材４−２とが、第１凸部５−１（１）と第２凹部６−２とがそれぞれ第１面と第２面との対向する位置になるように、また第１凹部６−１と第２凸部５−２（１）とがそれぞれ第１面と第２面との対向する位置になるように設けられている。そのため、隣り合う２つの照明器具２である第１照明器具２−１と第２照明器具２−２とにおいて、第１照明器具２−１の第１取付部材４−１の第１凸部５−１（１）と第２照明器具２−２の第２取付部材４−２の第２凹部６−２とは対向する位置になる。同様に、第１照明器具２−１の第１取付部材４−１の第１凹部６−１と第２照明器具２−２の第２取付部材４−２の第２凸部５−２（１）とは対向する位置になる。つまり、１つのＴバー１に隣り合う第１照明器具２−１と第２照明器具２−２とを取り付けると、対向する凸部と凹部とが嵌り合ってＴバー１に取り付けられることになる。したがって、１つのＴバー１に隣り合う第１照明器具２−１と第２照明器具２−２とを取り付ける場合に、２つの照明器具２が互いに干渉することなく取り付け可能である。また、第１凸部５−１（１）と第２凸部５−２（１）との幅Ｗ１は、第２凹部６−２と第１凹部６−１との幅Ｗ２と略同一である。そのため、２つの照明器具２の取付部材４が互いに嵌り合ってＴバー１に取り付けられると、２つの照明器具２が互いに支え合い、Ｔバー１に安定して固定される。
また、上記の通り、第１取付部材４−１と第２取付部材４−２との幅Ｗ７は、第１面と第２面との幅Ｗ８の半分以上である。特に、Ｔバー１に固定される部分の長さＷ７、つまり、第１取付部材４−１であれば、第１凸部５−１（１）の外側端部から第２凸部５−２（２）の外側端部までの長さＷ７が第１面の幅Ｗ８の半分以上である。そのため、１つのＴバー１に隣り合う２つの照明器具２を取り付けるのではなく、１つの照明器具２を単独で取り付ける場合であっても傾くことなく安定して取り付けすることができる。 Here, as shown to Fig.5 (a), the 1st convex part 5-1 (1) of the 1st attachment member 4-1 of the 1st lighting fixture 2-1, and the 2nd of the 2nd lighting fixture 2-2. It fits into the second recess 6-2 of the mounting member 4-2, and the first recess 6-1 of the first mounting member 4-1 of the first lighting fixture 2-1 and the second of the second lighting fixture 2-2. The second protrusion 5-2 (1) of the attachment member 4-2 is fitted and attached to the T bar 1. That is, as described above, the lighting fixture 2 (the first lighting fixture 2-1 and the second lighting fixture 2-2) includes the first convex portion including the first mounting member 4-1 and the second mounting member 4-2. 5-1 (1) and the second concave portion 6-2 are positioned so that the first surface and the second surface face each other, and the first concave portion 6-1 and the second convex portion 5-2 (1 ) Are provided so that the first surface and the second surface face each other. Therefore, in the 1st lighting fixture 2-1 and the 2nd lighting fixture 2-2 which are two adjacent lighting fixtures 2, the 1st convex part 5 of the 1st attachment member 4-1 of the 1st lighting fixture 2-1. -1 (1) and the second recess 6-2 of the second mounting member 4-2 of the second lighting fixture 2-2 are opposed to each other. Similarly, the 1st recessed part 6-1 of the 1st mounting member 4-1 of the 1st lighting fixture 2-1, and the 2nd convex part 5-2 of the 2nd mounting member 4-2 of the 2nd lighting fixture 2-2 ( The position is opposite to 1). That is, when the 1st lighting fixture 2-1 and the 2nd lighting fixture 2-2 which adjoin to one T bar 1 are attached, the convex part and recessed part which oppose will fit, and it will be attached to T bar 1. . Therefore, when attaching the 1st lighting fixture 2-1 and the 2nd lighting fixture 2-2 which adjoin the one T bar 1, the two lighting fixtures 2 can be attached without interfering with each other. The width W1 between the first convex portion 5-1 (1) and the second convex portion 5-2 (1) is substantially the same as the width W2 between the second concave portion 6-2 and the first concave portion 6-1. is there. Therefore, when the attachment members 4 of the two lighting fixtures 2 are fitted to each other and attached to the T bar 1, the two lighting fixtures 2 support each other and are stably fixed to the T bar 1.
Further, as described above, the width W7 between the first mounting member 4-1 and the second mounting member 4-2 is more than half of the width W8 between the first surface and the second surface. In particular, if the length W7 of the portion fixed to the T-bar 1, that is, the first mounting member 4-1, the second convex portion 5-2 from the outer end portion of the first convex portion 5-1 (1). The length W7 to the outer end of (2) is at least half of the width W8 of the first surface. Therefore, instead of attaching two lighting fixtures 2 adjacent to one T-bar 1, even if one lighting fixture 2 is attached alone, it can be stably attached without tilting.

また、上記の通り、Ｔバー１の掛部１１の幅Ｗ１０は、支部１２の幅Ｗ１１よりも狭い。さらに、支部１２の端部から掛部１１の逆側の端部までの幅Ｗ１２は、第１凸部５−１と第２凸部５−２との幅Ｗ９と略同一である。そのため、図５（ａ）（ｂ）に示すように、Ｔバー１の掛部１１と第１凹部６−１との間には若干のスペース（Ｗ１１−Ｗ１２）がある。同様に、Ｔバー１の掛部１１と第２凹部６−２との間との間には若干のスペース（Ｗ１１−Ｗ１２）がある。このスペース（Ｗ１１−Ｗ１２）は、図５（ｃ）に示す各爪部７（第１爪部７−１（１）、第１爪部７−１（２）、第２爪部７−２（１）、第２爪部７−２（２））の幅Ｗ１３よりも広い。したがって、１つのＴバー１に２つの照明器具２を取り付ける場合に、一方の照明器具２をＴバー１に取り付けた後に、他方の照明器具２をＴバー１に取り付けることができる。 Further, as described above, the width W10 of the hanging portion 11 of the T-bar 1 is narrower than the width W11 of the support portion 12. Furthermore, the width W12 from the end of the support portion 12 to the opposite end of the hanging portion 11 is substantially the same as the width W9 of the first convex portion 5-1 and the second convex portion 5-2. Therefore, as shown to Fig.5 (a) (b), there is some space (W11-W12) between the hook part 11 of T-bar 1 and the 1st recessed part 6-1. Similarly, there is a slight space (W11-W12) between the hook 11 of the T-bar 1 and the second recess 6-2. This space (W11-W12) has each nail | claw part 7 (1st nail | claw part 7-1 (1), 1st nail | claw part 7-1 (2), 2nd claw part 7-2 shown in FIG.5 (c).
