PROBLEM TO BE SOLVED: To provide a ditch cover that can be attached and fixed to a groove opening part more simply with a reduced number of components.SOLUTION: In a ditch cover 1, a cover body part 10 is provided with a frame body part 11, main members 12 and reinforcement members 13 intersecting the main members 12, and in the cover body part 10, a mounting and fixing part 20 mounts and fixes the cover body part 10 to a groove opening part D1 in which the cover body part is installed. The mounting and fixing part 20 is integrally provided with a fitting seat part 21 engraved with a screw groove part 23, and a pressing member 30 having a pressing head 40 for being pressed against a groove opening part internal surface D2 so as to oscillate, at the tip, is screwed to the fitting seat part 21 in such a manner of capable of being advanced or retreated.SELECTED DRAWING: Figure 1
【課題】部品点数を削減して溝開口部に対してより簡便に取付固定することが可能な溝蓋を提供する。【解決手段】枠体部１１と主部材１２と主部材１２と交差する補強部材１３を有する蓋本体部１０に蓋本体部１０が設置される溝開口部Ｄ１に対し蓋本体部１０を取付固定する取付固定部２０が設けられた溝蓋１であって、取付固定部２０はねじ溝部２３が刻設された取付座部２１を一体に備え、取付座部２１に先端に溝開口部内壁面Ｄ２に首振り可能に圧接する圧接頭部４０を備えた圧締部材３０が進退可能に螺着されている。【選択図】図１
