It is cut to a predetermined size, and is adhered on the upper surface of the slip washer 5 along the circumference thereof, and the connection portion 13b is substantially abutted to be adhered and integrated on the slip washer 5 in a ring shape. Therefore, the wavy vibration-isolating rubber 13 is not formed by punching in a ring shape, but has a large diameter when punched, and the loss of rubber is large and the productivity is deteriorated. First, it can be formed into a band-like shape, and can be stuck in a ring shape with the corrugated portion 13a inside, and even if the diameter is about 180 mm, it can be easily formed into a ring shape and stuck on the upper surface of the slip washer 5. Therefore, it can be manufactured at a reduced cost. Moreover, if the wavy anti-vibration rubber 13 is integrally attached to the upper surface of the slip washer 5 as described above, Due to the elasticity of the corrugated vibration-proof rubber 13, a good vibration-proof function can be achieved, and vibration transmitted to the sink 1 can be reduced.

Next, when the sink flange 7 is inserted into the sink adapter 3 fixed to the sink 1 so as to be inserted therein, as shown in FIG. 4, the sink flange 7 has a flange portion 7b on the upper surface. And a cylindrical portion 7a formed with an external male screw is formed to extend downward.
