To provide an opening/closing ditch cover that effectively prevents flipping up and improves operability to enable simple opening/closing operation while simplifying structure.SOLUTION: A ditch cover 1 in which a cover body 20 is pivotally supported on one end side of a receiving frame 10 so as to be openable and closable is provided with a cover-side engaging member 30 having a locking bar member 31 that protrudes from or is embedded into an open side end plate member 22a of the cover body, and a handle part 35 that is connected to the locking bar member and enables opening and closing of the cover body, on an open side of the cover body, the cover body cannot be opened when the locking bar member engages with a frame-side locking part 15 projecting inside an open-side end wall part 12a of the receiving frame when the locking bar member protrudes, and the cover body can be opened when the locking bar member is embedded in an open side end plate member side due to retreat of the handle part and an engagement state with the frame-side locking part is released.SELECTED DRAWING: Figure 2
【課題】構造の簡素化を図りながら、効果的に跳ね上げを防止するとともに操作性を向上させて簡易な開閉操作を可能とした開閉用溝蓋を提供する。【解決手段】蓋本体２０が受枠１０の一端側に開閉自在に軸支される溝蓋１であって、蓋本体の開放側には、蓋本体の開放側端板部材２２ａから突出または埋入するかんぬき部材３１と、かんぬき部材に接続されて蓋本体の開閉操作を可能とする把手部３５とを有する蓋側係合部材３０が設けられ、かんぬき部材の突出時に受枠の開放側端壁部１２ａの内側に突設された枠側係止部１５にかんぬき部材が係合されて蓋本体を開放不能とするとともに、把手部の後退によりかんぬき部材が開放側端板部材側に埋入されて枠側係止部との係合状態が解除されて蓋本体が開放可能となる。【選択図】図２
