PROBLEM TO BE SOLVED: To provide a ditch cover capable of being stably fixed to a lid receiver frame disposed in a ditch path.SOLUTION: A ditch cover includes a bolt housing 11 in which a housing air space 17 is formed, the housing air space receiving a head 33 of a fixing bolt 31 that is screwed to a lid receiver frame 41, the bolt housing being disposed in both side edges placed on the lid receiver frame 41. The ditch cover can improve safety standards regarding pedestrian's walking thereon and stably maintaining a state of fixation by the fixing bolt 31 for a relatively long period of time, since the fixing bolt 31 is attached to the bolt housing 11 in a state in which the head 33 is housed in the housing air space 17 by inserting the head 33 in the housing air space 17 via an insertion port 21 opening laterally and by inserting a screw 32 from one side end of a loose hole 22 opening laterally.SELECTED DRAWING: Figure 3
【課題】溝路に配設された蓋受枠に安定して固定することができる溝蓋を提供する。【解決手段】蓋受枠４１に乗載する両側縁に、該蓋受枠４１と螺着させる固定用ボルト３１の頭部３３を収容する収容空域１７が形成されたボルト収容部１１を備え、側方に開口する挿入口部２１を介して頭部３３を該収容空域１７へ挿入し且つ該側方に開放された遊嵌孔２２の一側端から螺子部３２を挿入することによって、該固定用ボルト３１が、頭部３３を該収容空域１７に収容した状態でボルト収容部１１に取り付けられるものであるから、歩行の際の安全性を向上できると共に、該固定用ボルト３１による固定状態を比較的長期に亘って安定して保持できる。【選択図】図３
