PROBLEM TO BE SOLVED: To reduce its labor while securing safety on opening-closing work of an opening-closing cover.SOLUTION: An opening-closing cover 1A comprises a fixing frame 2A and a cover body 3A for executing opening-closing operation by rotating around shaft members 31a and 31b journaled on its inside, the shaft members 31a and 31b are projected from a side surface with a line of passing at a right angle through an intermediate part of a pair of parallel sides of the cover body 3A as the axis, both end sides are arranged by being inserted into bearings 21a and 22a by a notch formed laterally long from a central part of the fixing frame 2A, a closing state is maintained by supporting a pair of edge sides of not passing the axis of the cover body 3A by receiving surfaces 20a and 20b of the fixing frame 2A, the edge side supported by dislocating-moving the cover body 3A by sliding the shaft members 31a and 31b in the bearings 21a and 22a, becomes a rotatable state by being disconnected from the receiving surface 20b, and the shaft members 31a and 31b slide the cover body 3A up to be positioned on the bearing 21a, 22a end part side, and is fully opened by putting its upper surface in a state of being close contact with or closely adjacent to a groove wall.SELECTED DRAWING: Figure 1
【課題】開閉蓋の開閉作業について安全性を確保しながらその労力を軽減する。【解決手段】固定枠２Ａとその内部で軸支された軸部材３１ａ，３１ｂを中心に回動させて開閉動作を行う蓋本体３Ａを備えた開閉蓋１Ａであって、軸部材３１ａ，３１ｂは蓋本体３Ａの１対の平行な辺の中間部を直角に通る線を軸線として側面から突設され両端側が固定枠２Ａの中央部から横長に形成した切り欠きによる軸受２１ａ，２２ａに挿通して配設されており、蓋本体３Ａの軸線が通らない対の辺側が固定枠２Ａの受け面２０ａ，２０ｂで支持されて閉鎖状態を維持し、軸部材３１ａ，３１ｂを軸受２１ａ，２２ａ内で摺動させて蓋本体３Ａをずれ動かすことで支持された辺側が受け面２０ｂから外れて回動可能な状態になり、蓋本体３Ａを軸部材３１ａ，３１ｂが軸受２１ａ，２２ａ端部側に位置するまで摺動させてその上面が溝壁に密着又は近接した状態にすることで全開になるものとした。【選択図】図１
