CYLINDRICAL BODY
To provide a cylindrical body that detachably fixes a manhole cover to a manhole frame.SOLUTION: A cylindrical body 1 is a cylinder buried in the ground, and has: a cylinder in which a through hole 20 penetrating in the radial direction is formed at one end in the axial direction; a lid 3 that is detachably attached to the one end of the cylinder, wherein the lid 3 has a hole formed in the radial direction aligned along with the through hole 20 in the radial direction with the lid 3 attached to one end; and a shaft body 4 having a shaft portion 41 inserted into the through hole 20 and the aligned hole from the radial direction of the cylinder and an attachment portion that can be detachably attached to the cylinder.SELECTED DRAWING: Figure 3
【課題】マンホール枠に対してマンホール蓋を着脱可能に固定する筒体を提供する。【解決手段】筒体１は、地中に埋設される筒であって、径方向に貫通する貫通孔２０が軸方向の一端部に形成された筒と、該筒の該一端部に着脱可能に取り付けられる蓋３であって、蓋３が該一端部に取り付けられた状態において、該径方向で貫通孔２０と並ぶ穴が該径方向に形成された蓋３と、該筒の該径方向から貫通孔２０及び該穴に挿入される軸部４１、及び該筒に着脱可能に取り付けられる取付部を備えた軸体４とを有する。【選択図】図３
