To provide a ditch cover hole closing cap difficult to be dislodged from between adjacent ditch covers with the mechanical strength improved in the direction in which the ditch cover expands.SOLUTION: A ditch cover hole closing cap 30 includes a plate-shaped top plate 50, an inner protrusion 52, a fixing portion 54, and a connecting portion 56. The top plate 50 closes an opening between the ditch covers. The inner protrusion 52 protrudes from the surface of the top plate 50 facing the inside of the ditch cover opening when the top plate 50 closes the ditch cover opening. The inner protrusion 52 is provided on the side of the top plate 50 that faces the interior of the opening between the ditch covers. The fixing portion 54 is arranged at a position on the opposite side of the inner protrusion 52 when viewed from the position of the top plate 50. The connecting portion 56 has a columnar portion 90 and a column holding portion 92. The columnar portion 90 is arranged so as to penetrate the inner protrusion 52. The column holding portion 92 holds the columnar portion 90 so that the columnar portion 90 and the fixing portion 54 can freely rotate with respect to the inner protrusion 52 about the central axis of the columnar portion 90 itself.SELECTED DRAWING: Figure 2
【課題】隣接する溝蓋間から外れ難くし、かつ、溝蓋が拡がる方向についての機械的強度を向上させる。【解決手段】溝蓋穴閉塞キャップ３０は、板状の天板部５０と内突出部５２と固定部５４と接続部５６とを備える。天板部５０は、溝蓋間開口を閉塞するためのものである。内突出部５２は、天板部５０のうち天板部５０が溝蓋間開口を閉塞するとき溝蓋間開口内部に対向する面から突出する。内突出部５２は、天板部５０のうち溝蓋間開口内部に対向する面に設けられる。固定部５４は、天板部５０の位置から見た場合の内突出部５２の向こう側となる位置に配置される。接続部５６が、柱状である柱状部９０と柱保持部９２とを有する。柱状部９０は、内突出部５２を貫通するように配置される。柱保持部９２は、柱状部９０および固定部５４が柱状部９０自身の中心軸を中心にして内突出部５２に対して自在に回転可能となるように柱状部９０を保持させる。【選択図】図２
