To provide a switchgear that makes it possible to easily perform a spring force adjustment work of a spiral spring without using a tool and without receiving influence of a case of a driving device.SOLUTION: A guide rail 15 being guide means, and a driving device 20 are housed inside a transom member 3 having an aperture 3A to be opened/closed using an inspection cover 11 and a door body 1 suspended from the rail 15 is guided by the rail to perform opening/closing movement. The driving device comprises: a take-up reel being housed inside a case 37 to deliverably take up a string-like member having an end connected to the door body 1; and a spiral spring in which return spring force for taking up the string-like member using the reel is accumulated when the string-like member is delivered from the reel. The spring has inner and outer ends connected to the reel's center shaft 35 and the reel. To an end of the center shaft extending to the outside of the case is attached a rotation operation member 36. The rotation operation member for rotating the center shaft has a protrusion 36A that is a protrusion part protruding below an undersurface 37A of the case.SELECTED DRAWING: Figure 5
【課題】渦巻きばねのばね力調整作業を工具を用いることなく、駆動装置のケースの影響を受けることなく容易に実施できる開閉装置の提供。【解決手段】点検カバー１１で開閉される開口部３Ａを有する無目部材３の内部にガイド手段であるガイドレール１５と駆動装置２０が収納され、レール１５から吊り下げられた扉体１はレールの案内で開閉移動する。駆動装置は、端部が扉体１に連結された紐状部材を繰り出し自在に巻き取るためにケース３７の内部に収納された巻取りリールと、このリールから紐状部材が繰り出されるときにリールで紐状部材を巻き取るための戻しばね力が蓄圧される渦巻きばねとを備え、このばねの内外端部はリールの中心軸３５とリールとに連結され、ケースの外側に延出した中心軸の端部に回転操作部材３６が取り付けられ、中心軸を回転させる回転操作部材はケースの下面３７Ａよりも下側へ突出した突出部となっている突部３６Ａを有する。【選択図】図５
