PROBLEM TO BE SOLVED: To provide an inspection door cover device capable of restraining foreign matter from gathering on an upper surface of an inspection door.SOLUTION: An inspection door cover device 4A is provided for covering an inspection door 2 from above when the inspection door 2 displaced between a door closing position for blocking up an inspection port 11 formed in the ceiling 1 and a door opening position for opening the inspection port 11 by extending downward from the ceiling 1, exists in the door closing position, and comprises a sheet 401 displaced between an overhang position of covering the inspection door 2 from above and a storage position of exposing an upper surface of the inspection door 2 by being deformed, a displacement device 406 for displacing the sheet 401 by interlocking with displacement of the inspection door 2 and a roller 402 for winding the sheet 401, and the sheet 401 is displaced to the storage position from the overhang position by being wound on the roller 402, and is displaced to the overhang position from the storage position by being sent out of the roller 402.SELECTED DRAWING: Figure 1
【課題】点検扉の上面に異物がたまることを抑制することができる点検扉カバー装置を得る。【解決手段】天井１に形成された点検口１１を塞ぐ閉扉位置と天井１から下方に延びて点検口１１が開く開扉位置との間で変位する点検扉２が閉扉位置にある場合に点検扉２を上方から覆う点検扉カバー装置４Ａであって、変形することによって、点検扉２を上方から覆う張出位置と点検扉２の上面が露出する収納位置との間で変位するシート４０１と、点検扉２の変位に連動してシート４０１を変位させる変位装置４０６と、シート４０１が巻かれるローラ４０２とを備え、シート４０１は、ローラ４０２に巻き取られることによって張出位置から収納位置に変位し、ローラ４０２から送り出されることによって収納位置から張出位置に変位する。【選択図】図１
