Claims

[Scope of utility model registration request]

When a circumferential groove 3 is formed on the upper surface of the lower member 2 constituting the manhole and the sealing material 6 filled in the circumferential groove 3 is press-joined on the lower surface of the upper member 1 constituting the manhole, the pressing surface A is flat. A joint between members of a precast manhole, characterized by:
