<p>PROBLEM TO BE SOLVED: To provide an inexpensive draining hose which is made out of raw material in a dechlorination series, reduces its parts in number, and can be easily executed because the draining hose in the past had too many component parts, was complex in an assembling process, and when it is burnt out, it produces gas in a chlorine series and waste, and these are thereby causes of environmental pollution. SOLUTION: A joining part 2 matching the bore diameter of a draining port at the side of a sink, is provided for one end of the draining hose comprizing soft synthetic raw material in a dechlorination series integrally formed by means of blow molding, concurrently a flange part 4 capable of incorporating a flat packing 3 is formed so as to be freely threadedly engaged with the draining port by means of a box nut 5 inserted through from the other end side, meanwhile, a joining part 7 matching the bore diameter of a draining port at the side of an under floor is formed at the other end, and a hose main body 1 at the intermediate part is formed into a bellows shape so as to allow strength and flexibility to be thereby maintained.</p> |
