SIDE DITCH LID AND SET OF SIDE DITCH AND SIDE DITCH LID
To prevent a side ditch lid from falling even if marginal parts on both sides in a width direction of a side ditch are different in height.SOLUTION: Projections 242, 243, 245 fixed to a lid body 210 protrude toward the inside of a side ditch when a side ditch lid 200 blocks the side ditch. One end in a width direction of the lid body 210 is higher than the other end when blocking the side ditch whose marginal parts on both ends in the width direction are different in height. The projections 242, 243, 245 are fixed to the other end side in the width direction of the lid body 210. One end in the width direction of the lid body 210 is supported by a side wall of one end in the width direction of the side ditch, while the other end in the width direction is supported by the marginal part in the width direction of the side ditch when the lid body blocks the side ditch. Distance D1 from one end in the width direction of the lid body 210 to the other ends in the width direction of the projections 242, 243, 245 is longer than the length L36 in the width direction of the side ditch.SELECTED DRAWING: Figure 3
【課題】側溝の幅方向の両側の縁部が異なる高さであっても脱落しないようにする。【解決手段】蓋本体２１０に固定された各突出部２４２、２４３、２４５は、側溝用蓋２００が側溝を閉塞したときに側溝の内部に向かって突出する。蓋本体２１０は、幅方向の両端の縁部の高さが異なる側溝を閉塞したとき、幅方向の一端の高さが他端の高さよりも高い。各突出部２４２、２４３、２４５は、蓋本体２１０の幅方向の他端側に固定されている。蓋本体２１０は、側溝を閉塞したとき、幅方向の一端が側溝の幅方向の一端の側壁に支持される一方、幅方向の他端部が側溝の幅方向の他端の縁部に支持され、蓋本体２１０の幅方向の一端から各突出部２４２、２４３、２４５の幅方向の他端までの距離Ｄ１は、側溝の幅方向の長さＬ３６よりも長い。【選択図】図３
