When the above-mentioned load acts on the drain pipe 2, the rear surface of the flange 34 tends to be peeled off from the outer surface of the side wall 1, but the inner peripheral edge of the flange 34 is thick and has a waist. Therefore, a part of the flange 34 peels off from the side wall 1 or the flange 34 starts from the peeled part as a starting point.
Does not peel off from the side wall 1 entirely. Moreover,
Since the thick inner cylinder portion 31 is inserted into the connection hole 11,
The connection with the drain pipe 2 is strengthened, and leakage accidents such as sewage are prevented.
