Lid lid frames have come to be used. The standard manhole size used for general sewerage is about 600
mm, the size of a relatively small one (small diameter) is, for example, about 300 mm, and it is being used for a wide range of purposes such as on public roads and in residential lands.

車両通行にも十分耐えることができる。A sewage system accommodated in such a relatively small (small-diameter) lid receiving frame is, for example, a public basin, which is made of synthetic resin such as vinyl chloride and provided for maintenance and the like. The lid has a structure operated from above. Because it is made of resin, it cannot be installed exposed on the ground surface due to the problem of strength, and is protected by the above-mentioned lid receiving frame. Since the lid receiving frame is made of cast iron such as spheroidal graphite cast iron,
It can withstand vehicle traffic sufficiently.

を生じた。However, for the convenience of inspection and maintenance, the public basin is as shallow as possible, and is often constructed with the ground raised near the ground surface, and a space for opening and closing the public basin lid is required. For this reason, it is required that the lid receiving frame covering the public square has a large internal space. For this reason, when the conventional lid receiving frame in which the lid and the frame are hinged is used, there is a possibility that a part of the hinge comes into contact with the public square and is damaged. As a result, when the conventional hinged lid receiving frame is used, it is difficult to sufficiently meet the demand for installation as shallow as possible, or it is necessary to use an unnecessarily large lid receiving frame. I had a problem.

In the lid receiving frame having no hinge connection structure, there is a problem that the lid is separated from the frame by opening the lid, so that the lid is easily lost or damaged.
