することを目的とするもので゛ある。[Detailed description of the invention] This invention involves fitting an upward-facing packing into the receiving frame side of the manhole cover in an annular shape, and as the manhole cover is fitted, its lower surface is pressed against the elastic part on the upper surface of the packing to prevent foul odors from leaking from the manhole. This manhole cover device relates to a manhole cover device designed to prevent the lid from rattling, and has a packing action that adapts to the manhole cover even if it is slightly distorted, and is advantageous in attaching, replacing, and preventing the packing from falling off. The purpose is to provide equipment.

従来のマンホール蓋装置においてパツキンを装着するの
はマンホール蓋側の裏面であるから、そのマンホール蓋
を受枠から外すときに脱落することが多く、老化したと
きの取換も簡単でなかった。In conventional manhole cover devices, the gasket is attached to the back side of the manhole cover, so it often falls off when the manhole cover is removed from the receiving frame, and it is not easy to replace it when it gets old.

また、パツキンを受枠側に取付けることもできるが、そ
の場合に、マンホール蓋が多少歪んでいると弾力不足の
ため密着が不良になる欠点があった。It is also possible to attach the gasket to the receiving frame, but in that case, if the manhole cover is slightly distorted, there is a drawback that the tightness will be poor due to insufficient elasticity.

本考案は後記実施例に説明するように受枠側への装着が
簡単であり、しかも該装着のときに豊かな弾力をもつよ
うに改良されたパツキンを受枠側に装着して弾力不足そ
の他の欠点を除いたものである。As explained in the examples below, the present invention is easy to attach to the receiving frame side, and when it is installed, an improved packing that has rich elasticity is attached to the receiving frame side. is excluded.

本考案の一実施例を添付図面について説明する。An embodiment of the present invention will be described with reference to the accompanying drawings.

不良にするおそれはない。The elastic portion 15 is caused by the weight of the manhole cover 7 to tighten the hollow hole 1.
4 and deforms the semicircular protrusion 13 to be pressed against the contact surface 9. This prevents odor from leaking from the opening 6, wobbling of the manhole cover 7, etc., and prevents the manhole cover 7 made of cast metal from aging over time. Even if it is slightly distorted due to changes, etc., there is no risk of deteriorating the sealing action.
