PROBLEM TO BE SOLVED: To provide a curtain opening/closing device capable of being used continuously while being attached on a curtain and semi-automatically opening/closing the curtain by a reel using a spiral spring.SOLUTION: The curtain opening/closing device includes: a reel 21 accumulating force in a spiral spring when a long body 22 is drawn out and winding-up the long body by means of the force; and an interlock part 23 interlocking the curtain 11 and the long body 22. The reel is attached at a fixed side portion such as one end of a curtain rail 14. The long body 22 is folded in a folding part 25 on the other end of the curtain rail 14 and suspended from a guide part 24. When a tip side of the long body 22 is pulled by a person, the long body 22 is drawn out and the curtain 11 gets closed. When opening the curtain, the long body 22 is wound-up by means of force accumulated in the spiral spring of the reel 21 and the curtain 11 gets opened automatically.SELECTED DRAWING: Figure 1 【課題】カーテンに取り付けた状態のままで使い続けることができ、ゼンマイバネを用いたリールによって、カーテンの開閉を半自動で行うことができるようにしたカーテンの開閉装置の提供を図る。【解決手段】長尺体２２を引き出す際にゼンマイバネに力が蓄えられと共にその力によって巻き取りをなすリール２１と、カーテン１１と長尺体２２とを連動させる連動部２３とを備える。リールはカーテンレール１４の一端などの固定側部位に取り付けられる。長尺体２２は、カーテンレール１４の他端の折り返し部２５により折り返して、ガイド部２４から垂下される。長尺体２２の先端側を人が引っ張ると、長尺体２２が繰り出されて、カーテン１１が閉まる。開く際には、リール２１のゼンマイバネに蓄えられた力で長尺体２２が巻き取られて、カーテン１１が自動的に閉じる。【選択図】図１
