以上に説明した照明装置１０００は、以下の効果を奏する。
（１）プルスイッチ１４０が本体部１１０の凹部１１１の内部に収納されるので、器具本体１００の外部に形成される構造物への影響が小さく、照明装置１０００の大きさを小さくすることができる。つまり、プルスイッチ１４０なしの照明装置の大きさと同じ程度のサイズとすることができる。
（２）プルスイッチ１４０の引っ張り方向が、横方向である。つまり、引っ張り部１４３の引っ張り方向が、側壁部１１３−２から側壁部１１３−１へ向かう方向である。言い換えれば、引っ張り部１４３の引っ張り方向が、照明装置１０００の短手方向（図１）となる。照明装置１０００では短手方向へ引っ張る場合は照明装置のサイズアップの影響が少ない。この点からも照明装置のサイズアップを抑制できる。
（３）照明装置１０００では、プルスイッチ１４０（引っ張り部１４３）と、引き紐１６０との間に、ワイヤー１５０を介在させた。よって、引き紐１６０が切れた際にも交換が容易である。
（４）照明装置１０００では、ワイヤー１５０のワイヤー側連結部１５２が傾斜部１１４−１の傾斜部貫通孔１１４Ｈを通り抜けているので、引き紐１６０が切れた場合でも、引き紐１６０をワイヤー側連結部１５２に取り付けることが容易である。
また図１０（照明器具１００４）の場合はワイヤー側連結部１５２が本体部１１０の外部に露出しているので、引き紐１６０が切れた場合でも、引き紐１６０をワイヤー側連結部１５２に取り付けることが容易である。
（５）さらにワイヤー１５０が、本体部１１０の凹部１１１の内部から外へ出た直後に、ワイヤー１５０をワイヤー屈曲部分１５３で屈曲させて、傾斜部１１４−１の立ち上がり方向（図５の矢印Ｘの方向）に向かわせて、ワイヤー１５０が傾斜部１１４−１にぶつかる傾斜部１１４−１の箇所に傾斜部貫通孔１１４Ｈを形成している。そのため、傾斜部貫通孔１１４Ｈは側壁部１１３−１の立ち上がり終了する終端部分であり傾斜部が始まる終端部分である傾斜部開始位置に形成されるので、傾斜部の傾斜の異なる照明装置（照明装置１００２，１００３）のそれぞれに対して、傾斜部の傾斜の違いに左右されず、傾斜部貫通孔１１４Ｈを形成することができる。よって傾斜部の傾斜の違いに左右されず、照明装置のサイズアップを抑制できる。 The lighting device 1000 described above has the following effects.
(1) Since the pull switch 140 is housed inside the recess 111 of the main body 110, the influence on the structure formed outside the fixture main body 100 is small, and the size of the lighting device 1000 can be reduced. . That is, the size of the lighting device without the pull switch 140 can be approximately the same as that of the lighting device.
(2) The pulling direction of the pull switch 140 is the horizontal direction. That is, the pulling direction of the pulling portion 143 is a direction from the side wall portion 113-2 to the side wall portion 113-1. In other words, the pulling direction of the pulling portion 143 is the short direction of the lighting device 1000 (FIG. 1). When the lighting device 1000 is pulled in the short direction, the size of the lighting device is less affected. From this point as well, an increase in the size of the lighting device can be suppressed.
(3) In the lighting device 1000, the wire 150 is interposed between the pull switch 140 (pulling portion 143) and the drawstring 160. Therefore, even when the drawstring 160 is cut, the replacement is easy.
(4) In the lighting device 1000, since the wire-side connecting portion 152 of the wire 150 passes through the inclined portion through hole 114H of the inclined portion 114-1, even when the drawstring 160 is cut, the drawstring 160 is connected to the wire. It is easy to attach to the part 152.
In the case of FIG. 10 (lighting fixture 1004), since the wire-side connecting portion 152 is exposed to the outside of the main body 110, even when the drawstring 160 is cut, the drawstring 160 is attached to the wire-side connecting portion 152. Is easy.
(5) Immediately after the wire 150 goes out of the inside of the concave portion 111 of the main body 110, the wire 150 is bent at the wire bending portion 153, and the rising direction of the inclined portion 114-1 (arrow X in FIG. 5). , A slanted portion through hole 114H is formed at a position of the slanted portion 114-1 where the wire 150 hits the slanted portion 114-1. Therefore, since the inclined portion through hole 114H is formed at the inclined portion start position which is the terminal portion where the rising end of the side wall portion 113-1 ends and the inclined portion starts, the illumination device (illumination device) having a different inclination of the inclined portion. 1002, 1003), the inclined portion through hole 114H can be formed without being affected by the difference in the inclination of the inclined portion. Therefore, it is possible to suppress an increase in the size of the lighting device regardless of the difference in the inclination of the inclined portion.

以上の照明装置では、引っ張り部１４３を棒状体として説明したが、これに限らず、引っ張り部１４３は紐状のものを用いても構わない。この場合、例えば、引っ張り部１４３の線径を引き紐１６０の線径よりも太くする。つまり、引っ張り部１４３の紐状のものの強度を、引き紐１６０の強度よりも強くする。これによって、引き紐１６０が切れるような強さで引っ張られる場合であっても、引っ張り部１４３が断線することを抑制できる。 In the above lighting device, the pulling portion 143 has been described as a rod-shaped body, but the present invention is not limited to this, and the pulling portion 143 may be a string-shaped one. In this case, for example, the wire diameter of the pulling portion 143 is made larger than the wire diameter of the drawstring 160. That is, the strength of the string-shaped pulling portion 143 is made stronger than the strength of the pulling string 160. Accordingly, even when the pull cord 160 is pulled with such strength that the pull cord 160 is cut, it is possible to prevent the pull portion 143 from being disconnected.
