COVER FOR UNDERGROUND STRUCTURE
PROBLEM TO BE SOLVED: To provide a cover for an underground structure capable of generating appropriate biting force into a receiving frame of a cover body, when the cover body is closed on the receiving frame.SOLUTION: In a cover for an underground structure having a cover body 10 and a receiving frame 20 that openably supports the cover body on an inner peripheral part, a cutout part 13, into which a tip of a crowbar 30 for opening/closing the cover is inserted, is formed on an outer peripheral edge of the cover body 10, and a receiving frame engagement part 22 is formed on the inner peripheral part of the receiving frame 20 at a position facing the cutout part 13 when the cover body is closed on the receiving frame, the receiving frame engagement part allowing the tip of the crowbar 30 for opening/closing the cover to be engaged thereon while being inserted into the cutout part 13.SELECTED DRAWING: Figure 4
【課題】蓋本体を受枠に閉蓋する際に、蓋本体の受枠への適度な食い込み力を発生させることができる地下構造物用蓋を提供する。【解決手段】蓋本体１０と、この蓋本体を内周部で開閉可能に支持する受枠２０とを備えた地下構造物用蓋において、蓋本体１０の外周縁部に、蓋開閉用バール３０の先端が挿入可能な切欠き部１３を形成し、受枠２０の内周部には、蓋本体を受枠に閉蓋した際に切欠き部１３と相対する位置に、切欠き部１３に挿入した蓋開閉用バール３０の先端が係止可能な受枠係止部２２を形成した。【選択図】図４
