By providing 1, the displacement between the movement change of the boss 42 and the movement change of the flange 41 can be effectively absorbed.
A sleeve pipe 44 made of vinyl chloride is fitted into the inner surface of the large-diameter boss 42. The inner diameter of the sleeve tube 44 is substantially the same as the inner diameter of the small-diameter boss 43, and is set to a size in which the manhole joint 2 is inserted. A stainless steel band 4 is provided on the outer surface of the outer boss 42 and the smaller boss 43.
