DRAINPIPE SOCKET, AND CONNECTING METHOD FOR DRAINPIPE

摘要

PURPOSE: To reduce cost with the number of parts decreased while having labor in connecting work. ;CONSTITUTION: In a drainpipe socket 5A, a small tubular part 27 is provided, extending downward from the lower end of an inner tube 14. The outer diameter of the small tubular part 27 is smaller than the outer diameter of the inner tube 14. A drainpipe 3B, smaller in the inner diameter than the outer diameter of the inner tube 14 because of its thickness, can be connected to the small tubular part 27. Therefore a drainpipe, althoug having the inner diameter smaller than the outer diameter of the inner tube, can be connected directly without using a joint.;COPYRIGHT: (C)1995,JPO
