<P>PROBLEM TO BE SOLVED: To reduce the assembling labor, the material cost and the manufacturing cost by improving a seal member. <P>SOLUTION: This joint for a flexible tube includes a cylindrical body 11 and a stopper ring 61 integrally joined on the same axis. A corrugated tube 2 exposed in crest parts 4 and trough parts 5 by eliminating a tip part of a cover body 3 in a flexible tube 1 is inserted into the cylindrical body 11 through the stopper ring 61 to join the corrugated tube 2 with the cylindrical body 11. An annular seal member 31 constituted of a center layer 32 and an outer wrapping layer 33 is interposed between the inner surface of the cylindrical body 11 and the corrugated tube 2. The seal member 31 is structured by including a rubber material and a fire resistant foaming material in the center layer 32 and including a rubber material in the outer wrapping layer 33. <P>COPYRIGHT: (C)2013,JPO&INPIT |
