An outer cylinder portion 31 made of a rubber-like elastic body is adapted to be passed through the tube 20 and brought into close contact with the tube 20. A water-expansion sponge rubber 56 is attached to the inner surface near the tip of the outer tubular portion 31, and the outer surface is fastened with a fastening band. The insertion portion 32 made of a rubber-like elastic body is located in the drilled portion 11 through the pipe 20, and is coaxially connected to the outer cylinder portion 31.
The flange portion 33 formed of a rubber-like elastic body is provided so as to project at the boundary between the outer cylinder portion 31 and the insertion portion 32, and is bonded to the outer surface of the peripheral wall 10. An annular expansion / contraction portion 35 is provided on the flange portion 33 near the outer cylinder portion 31 so that the displacement of the pipe 20 can be followed when the pipe 20 is inclined as shown in FIG. In addition, as the expansion / contraction portion 35, the flange portion 33 is used.
Although the projections (FIG. 2) or the corrugations (FIG. 3) formed in the direction perpendicular to the plane of FIG. 3 are shown, the present invention is not limited to these as long as they have the same function. 4
1, 42 and 43 are joint mortar, joint filler and joint packing, respectively.

負担が少なくなり、周壁１０から剥離することはない。Since the flat plate-shaped flange portion 33 is provided with the expansion and contraction portion 35, it is easy to remove the mold from the die molding.
When the problem of shape setting is solved and displacement occurs due to unequal subsidence as shown in FIG. 3, part of the expandable part 35 expands P and the other part contracts Q, easily following the displacement. Therefore, the load on the flange portion 33 is reduced, and the flange portion 33 is not peeled off from the peripheral wall 10.
