It has been stopped.

次に、灯具本体11の枠体13への取付手順について説明する。
まず、灯具本体11が、枠体13の枠本体21の下方に配置される。
次に、図6に示すように、灯具本体11が枠体13の枠本体21の内周側から灯具取付枠部23の内周側へと挿入されていく。
このとき、灯具本体11は、枠体13に対して位置決めされていない。
Next, a procedure for attaching the lamp body 11 to the frame 13 will be described.
First, the lamp body 11 is disposed below the frame body 21 of the frame body 13.
Next, as shown in FIG. 6, the lamp main body 11 is inserted from the inner peripheral side of the frame main body 21 of the frame 13 to the inner peripheral side of the lamp mounting frame portion 23.
At this time, the lamp body 11 is not positioned with respect to the frame body 13.

次に、図7に示すように、灯具本体11の挿入凸部45が枠体13の灯具取付枠部23の切欠部43に挿入される。
これにより、灯具本体11が枠体13に対して位置決めされる。
続いて、図8に示すように、灯具本体11は、挿入凸部45が枠体13の灯具取付枠部23の切欠部43に挿入された後に、位置A1から位置A2まで図8中の時計回転方向に回動される。
Next, as shown in FIG. 7, the insertion convex portion 45 of the lamp body 11 is inserted into the notch 43 of the lamp mounting frame portion 23 of the frame body 13.
Thereby, the lamp body 11 is positioned with respect to the frame body 13.
Subsequently, as shown in FIG. 8, the lamp body 11 includes the timepiece in FIG. 8 from the position A <b> 1 to the position A <b> 2 after the insertion convex portion 45 is inserted into the notch 43 of the lamp mounting frame portion 23 of the frame body 13. It is rotated in the direction of rotation.

このとき、挿入凸部45は、灯具取付枠部23の円環板部42の上面に配置されているために、灯具本体11は枠体13の灯具取付枠部23に保持されている。
灯具本体11が図8中の時計回転方向にあらかじめ定められた角度だけ回動されることにより、固定凸部46が灯具取付枠部23の切欠部43に位置される。
At this time, since the insertion convex portion 45 is disposed on the upper surface of the annular plate portion 42 of the lamp mounting frame portion 23, the lamp main body 11 is held by the lamp mounting frame portion 23 of the frame body 13.
When the lamp body 11 is rotated by a predetermined angle in the clockwise direction in FIG. 8, the fixed convex portion 46 is positioned in the notch portion 43 of the lamp mounting frame portion 23.

図9に示すように、灯具本体11の回動に伴い、固定凸部46の固定ねじ47が灯具取付枠部23の切欠部43においてねじ止溝44に挿入される。
そして、ねじ止溝44に挿入されている固定ねじ47がねじ込まれることにより、灯具本体11が枠体13の所定位置に固定されることになる。
従って、枠体13に対して灯具本体11を簡単に位置決めできる。
As shown in FIG. 9, with the rotation of the lamp body 11, the fixing screw 47 of the fixing projection 46 is inserted into the screw retaining groove 44 at the notch 43 of the lamp mounting frame 23.
The lamp body 11 is fixed at a predetermined position of the frame 13 by screwing the fixing screw 47 inserted into the screw retaining groove 44.
Therefore, the lamp body 11 can be easily positioned with respect to the frame body 13.

このように、電線保持部41と切欠部43とが対応する挿入状態において枠体13に対して灯具本体11が挿入可能であり、挿入状態から枠体13に対して灯具本体11が所定角度回動される固定状態において枠体13に対して灯具本体11が固定される。
そのため、電線保持部41に保持されて枠体13の枠本体21および灯具取付枠部23の内側に配策されている電源線16を有する灯具本体11が、枠体13に位置決めされた後に、枠体13の灯具取付枠部23にねじ止めされる。
従って、灯具本体11の枠体13への取り付けに際して、電源線16が枠体13の枠本体21および灯具取付枠部23に接触することがない。
Thus, the lamp body 11 can be inserted into the frame body 13 in the insertion state in which the electric wire holding portion 41 and the cutout portion 43 correspond to each other, and the lamp body 11 can be rotated a predetermined angle with respect to the frame body 13 from the insertion state. The lamp body 11 is fixed to the frame 13 in the fixed state that is moved.
Therefore, after the lamp body 11 having the power supply line 16 that is held by the electric wire holding portion 41 and arranged inside the frame body 21 and the lamp mounting frame portion 23 of the frame body 13 is positioned on the frame body 13, Screwed to the lamp mounting frame portion 23 of the frame 13.
Therefore, when the lamp body 11 is attached to the frame body 13, the power line 16 does not contact the frame body 21 and the lamp attachment frame portion 23 of the frame body 13.

以上、説明した本発明に係る一実施形態の照明器具10によれば、灯具本体11が枠体13に組付けられる際に、電源線16が電線保持部41の内側に保持されて、枠体13の枠本体21および灯具取付枠部23から内側に離れて配策される。
従って、照明器具10によれば、電源線16の挟み込みを防止できる。
As mentioned above, according to the lighting fixture 10 of one Embodiment which concerns on this invention demonstrated, when the lamp main body 11 is assembled | attached to the frame 13, the power wire 16 is hold | maintained inside the electric wire holding part 41, and a frame 13 is arranged away from the frame main body 21 and the lamp attachment frame portion 23 inward.
Therefore, according to the luminaire 10, the power supply line 16 can be prevented from being caught.

また、照明器具10によれば、挿入凸部45が切欠部43に挿通された後に灯具本体11の回動に伴い、固定凸部46の固定ねじ47が切欠部43のねじ止溝44に挿入されてねじ込まれる。
従って、照明器具10によれば、枠体13に対して灯具本体11を簡単に位置決め固定できるので、組立作業性を向上できる。
Further, according to the lighting fixture 10, the fixing screw 47 of the fixing protrusion 46 is inserted into the screw stop groove 44 of the notch 43 as the lamp body 11 rotates after the insertion protrusion 45 is inserted into the notch 43. And screwed.
Therefore, according to the luminaire 10, since the lamp body 11 can be easily positioned and fixed with respect to the frame 13, the assembly workability can be improved.

なお、本発明の照明器具において補助反射板、電源ケース、パネル等は、前述した一実施形態に限定されるものでなく、適宜な変形や改良等が可能である。   In addition, in the lighting fixture of this invention, an auxiliary | assistant reflector, a power supply case, a panel, etc. are not limited to one Embodiment mentioned above, A suitable deformation | transformation, improvement, etc. are possible.
