And this terminal block block 25 is attached to the attachment member 21 using a screw etc. in the state in which at least one part was accommodated in the accommodating part 213, for example.

次に、光源ユニット２の組立手順について説明する。まず最初に、作業者は、電源装置２４及び端子台ブロック２５をそれぞれ取付部材２１の上面側に取り付け、さらに電源装置２４と端子台ブロック２５の間を電線により接続する。その後、作業者は、係止爪２１１ｃによりＬＥＤ基板２２を取付部材２１の底面部２１１に固定し、さらにＬＥＤ基板２２のコネクタ２２３から導出する電線を取付部材２１の底面部２１１に設けた孔２１１ａに通した後、その端部を電源装置２４に接続する。そして最後に、作業者は、開口側を上向きにした状態でカバー部材２３を取付部材２１に組み付ける。このとき、カバー部材２３の一方（図５中の右側）の突壁部２３３に設けた突起部２３３ａは、取付部材２１の側面部２１２に設けた凸部２１２ｂを乗り越えて傾斜部２１２ａの先端部と係合し、且つ、突壁部２３３は外側から凸部２１２ｂに当接する。またこのとき、カバー部材２３の他方（図５中の左側）の突壁部２３３に設けた突起部２３３ａは、取付部材２１の側面部２１２に設けた傾斜部２１２ａに摺動しながら上方に移動していき、所定の取付位置まで移動すると傾斜部２１２ａの先端部と係合する。以上のような手順に従って、光源ユニット２が組み立てられる。   Next, the assembly procedure of the light source unit 2 will be described. First, the operator attaches the power supply device 24 and the terminal block block 25 to the upper surface side of the attachment member 21, respectively, and further connects the power supply device 24 and the terminal block block 25 with electric wires. Thereafter, the operator fixes the LED substrate 22 to the bottom surface portion 211 of the mounting member 21 by the locking claw 211c, and further, the hole 211a provided in the bottom surface portion 211 of the mounting member 21 with the electric wire led out from the connector 223 of the LED substrate 22 Then, the end is connected to the power supply device 24. Finally, the operator attaches the cover member 23 to the attachment member 21 with the opening side facing upward. At this time, the protruding portion 233a provided on the protruding wall portion 233 on one side (right side in FIG. 5) of the cover member 23 gets over the convex portion 212b provided on the side surface portion 212 of the mounting member 21, and the tip portion of the inclined portion 212a. And the protruding wall portion 233 comes into contact with the convex portion 212b from the outside. At this time, the protrusion 233a provided on the other protruding wall 233 of the cover member 23 (left side in FIG. 5) moves upward while sliding on the inclined portion 212a provided on the side surface 212 of the mounting member 21. Then, when it moves to a predetermined mounting position, it engages with the tip of the inclined portion 212a. The light source unit 2 is assembled according to the above procedure.

続けて、照明器具Ａの施工手順について説明する。まず最初に、作業者は、室内側に露出する上記電源線を器具本体１に設けた孔１１１ａに通し、さらに天井材１００を通して室内側に露出する吊ボルト２００を孔１１１ｂに通した後、吊ボルト２００にナット３００をねじ込んで器具本体１を天井材１００に固定する。その後、作業者は、上記電源線を端子台２５１に接続し、少なくとも電源装置２４及び端子台ブロック２５が収容凹部１１に収容されるようにして、例えば器具本体１及び取付部材２１にそれぞれ設けた嵌合構造（図示せず）により光源ユニット２を器具本体１に取り付ける。以上のような手順に従って、照明器具Ａが天井に施工される。   Then, the construction procedure of the lighting fixture A is demonstrated. First, the operator passes the power line exposed to the indoor side through the hole 111a provided in the instrument body 1, and further passes the suspension bolt 200 exposed to the indoor side through the ceiling material 100 through the hole 111b. A nut 300 is screwed into the bolt 200 to fix the instrument body 1 to the ceiling material 100. After that, the operator connects the power line to the terminal block 251, and at least the power supply device 24 and the terminal block block 25 are accommodated in the accommodating recess 11, for example, provided on the instrument body 1 and the attachment member 21, respectively. The light source unit 2 is attached to the instrument body 1 by a fitting structure (not shown). The lighting fixture A is constructed on the ceiling according to the above procedure.

ここで、図５は光源ユニット２を組み付けた状態を示している。この状態では、カバー部材２３の一方（図５中の右側）の突壁部２３３が取付部材２１の側面部２１２に設けた凸部２１２ｂに外側から当接しており、これにより取付部材２１に対してカバー部材２３をがたつきなく取り付けることができる。また、例えば電源装置２４に接続された電線４００を取付部材２１に固定する際に、凸部２１２ｂの裏側に設けた溝２１２ｄに電線４００を沿わせることで電線４００を仮保持させることができる。これにより、従来例のように電線４００を手で押さえなくてもいいので、電線４００を取付部材２１に固定する際の作業性が向上するという利点がある。さらに、凸部２１２ｂを側面部２１２に設けることで、側面部２１２の強度を高めることもできる。また、取付部材２１に対して電源装置２４をねじ固定する場合には、側面部２１２の傾斜部２１２ａと凸部２１２ｂの間に形成された窪み２１２ｃに固定ねじを配置することで、凸部２１２ｂよりも固定ねじが引っ込んだ状態でねじ固定することができる。   Here, FIG. 5 shows a state in which the light source unit 2 is assembled. In this state, one protruding wall portion 233 of the cover member 23 (right side in FIG. 5) is in contact with the convex portion 212 b provided on the side surface portion 212 of the mounting member 21 from the outside. The cover member 23 can be attached without rattling. For example, when the electric wire 400 connected to the power supply device 24 is fixed to the attachment member 21, the electric wire 400 can be temporarily held by placing the electric wire 400 along the groove 212d provided on the back side of the convex portion 212b. Thereby, since it is not necessary to hold down the electric wire 400 by a hand like the prior art example, there exists an advantage that the workability | operativity at the time of fixing the electric wire 400 to the attachment member 21 improves.
